Build a Blockchain & Cryptocurrency | Full-Stack Edition review for 2025

In our review of this course, we try to help you answer all of your most important questions about Build a Blockchain & Cryptocurrency | Full-Stack Edition as quickly and efficiently as possible, so that you can determine whether this online education training is worth your time and money.

Feel free to jump to whatever question you want answered the most.

Here’s what you’ll learn:

Why use BAB&C|FE as an abbreviation of the course name?

During our Build a Blockchain & Cryptocurrency | Full-Stack Edition course review, you might sometimes see us refer to it as BAB&C|FE for the following 2 reasons:

1. We created the acronym by taking the first letter of every word (which was very ingenious and innovative, we know)
2. We’re lazy and BAB&C|FE is simpler and easier for reviewing purposes

The full course name is 56 characters long, including blanks, while BAB&C|FE is 8 characters long.

You do the math.

Okay, we’ll do the math. We’re saving 48 characters every time we use BAB&C|FE.

So, just a heads up that we’ll be using this abbreviation sometimes, so you’re not left scratching your head and wondering what the heck we’re talking about whenever we refer to BAB&C|FE throughout the remainder of this review.

Is the Build a Blockchain & Cryptocurrency | Full-Stack Edition course for you?

To determine whether David Joseph Katz’s Udemy course is a good fit for you or not, ask yourself the following questions down below.

The more you answer “yes” to each question, the more likely it is that you’ll like this course.

Can you understand what David Joseph Katz’s course is about in 30 seconds or less?

Hopefully, you can easily grasp in 10 seconds or less what this online course is about simply by taking a look at the title that David Joseph Katz chose for the course, “Build a Blockchain & Cryptocurrency | Full-Stack Edition”, as well as its subtitle: “Full-stack blockchain programming course! A backend + frontend with Node.js, Jest, Express, React, Heroku, & more!”.

This combo of title and subtitle should be enough to communicate the purpose of the training if David Joseph Katz is a good, clear communicator (which, of course, you want in a teacher).

In our opinion, if you still don’t know what BAB&C|FE is about after looking at these two things, then this is a red flag, and you might be better off not taking this class.

Among other things, it means David Joseph Katz hasn’t clearly and accurately conveyed what the course is about and might not be the best teacher for you.

For similar reasons, it’s important that you’re able to clearly understand what Build a Blockchain & Cryptocurrency | Full-Stack Edition is all about from the first few lines of the course description.

So take just a few seconds to read the opening lines down below and see what you think of them. 

Opening lines of David Joseph Katz’s official description of BAB&C|FE

White walkers stalking you in the night? Death eaters knocking down your door?

…

Well, sounds like you’re looking to build a blockchain and cryptocurrency! Having your own blockchain and cryptocurrency is the number one way to get rid of threats both magical and technical!

(Read more about this course on the official course page.)

Does BAB&C|FE pass the 30 Seconds Test?

You can read a lot more about Build a Blockchain & Cryptocurrency | Full-Stack Edition on the official course page on Udemy, but the point is this: are the title, subtitle, and just the first few lines of the description enough to help you understand what the course is about?

If so, David Joseph Katz has done a good job and can be considered more trustworthy and a good communicator, which are important qualities for any teacher.

And, if not, maybe you’re better off looking at other Development classes that are more clearly defined and more tailored to your specific interests.

Did Build a Blockchain & Cryptocurrency | Full-Stack Edition appeal to you in 30 seconds or less?

Now that you’ve done the 30 Second Test with BAB&C|FE above, what is your gut reaction to this Development course with only the basic information of its title, subtitle, and the first few opening lines of its official course summary?

Did David Joseph Katz do a good job conveying its subject matter, and did it immediately get your attention and appeal to you?

If so, David Joseph Katz’s online course is certainly worth considering some more.

But if not, perhaps it’s in your best interest to consider some other Development courses instead, because clear communication and being able to hook and maintain your interest are two very important qualities for your online learning success.

Does David Joseph Katz sound like a course instructor you’d like to learn from?

You’ve already learned how to use The 30 Second Test to make a quick evaluation of whether the BAB&C|FE course is worth taking.

We have a similar 15 Second Bio Test where you read only the first few lines of an instructor’s background — in this case, David Joseph Katz’s background — and then you make a quick, snap judgment as to whether you think the instructor would be ideal for you.

There is no right or wrong answer. It’s just about going with your gut instinct. What might appeal to one potential student might alienate another, and vice versa.

(FYI, all Udemy instructors, including David Joseph Katz, have a Udemy profile on their course page, so you can easily check for a bio and background on the Udemy website that way. We’re only including the first few lines of the bio down below for The 15 Second Bio Test).

Opening lines from David Joseph Katz’s Udemy bio

David is a software engineer at Zendesk, with a Bachelor of Computer Science from the University of San Francisco.

What did you think about David Joseph Katz after reading just the first few lines of the bio above?

After reading just the first few lines about David Joseph Katz, did it make you more or less interested in taking the BAB&C|FE course?

And did it make you feel like David Joseph Katz was more or less credible and qualified to teach Build a Blockchain & Cryptocurrency | Full-Stack Edition?

Finally, overall, did you feel like you’d receive the proper training from the instructor of this Development course?

As always, we encourage you to listen to your gut instinct, which is different for every student.

Are the BAB&C|FE lessons clear, specific, and organized well?

Part of the (good) problem with Udemy’s online courses, such as the Build a Blockchain & Cryptocurrency | Full-Stack Edition course, is that the instructors are constantly updating them, including adding and renaming lessons.

So it makes no sense whatsoever for us to list out all the modules and lessons in the BAB&C|FE course here, because you can just as easily go to the Udemy course page and get all the up to date course structure as of right now.

We do, however, have some tips about reviewing David Joseph Katz’s course structure, so that you can get a better sense of whether this program is worth your time or not.

In a nutshell, you want to scan the the titles of the different sections and lessons of the course, and verify that they are clearly relevant to the course’s name, Build a Blockchain & Cryptocurrency | Full-Stack Edition, as well as the course’s subtitle, Full-stack blockchain programming course! A backend + frontend with Node.js, Jest, Express, React, Heroku, & more!.

If the section names and lessons are clear, specific, and relevant, then it’s a good sign that BAB&C|FE is potentially a good, useful course for you, and you can have more confidence in David Joseph Katz’s teaching abilities and lesson planning.

On the other hand, if the module names are confusing, vague, or irrelevant, then this is a red flag, which might indicate that the program is worth skipping.

Have you taken some free lessons from David Joseph Katz that you enjoyed?

Have you already learned something from David Joseph Katz that you valued or enjoyed?

For example, does the Build a Blockchain & Cryptocurrency | Full-Stack Edition training have some free lessons that you can try? (Almost all Udemy instructors will give you at least one or two lessons for free to help you make a better, more informed decision before enrolling in their course.)

But if you weren’t able to get any BAB&C|FE lessons for free, have you perhaps watched a YouTube video by David Joseph Katz, or perhaps come across this instructor’s thoughts on Quora, Facebook, LinkedIn, Github, Reddit, or some other platform?

Or have you perhaps even taken one of David Joseph Katz’s free courses or free webinars? (Many online teachers offer these freebies, which is a great way to get to know them and evaluate their teaching methods before buying one of their courses.)

In any case, the more familiar you are with David Joseph Katz’s teaching methods, and the more you enjoy them, the more likely it is that Build a Blockchain & Cryptocurrency | Full-Stack Edition will be a good fit for you.

(P.S.: We strongly encourage you to seek out some free instruction from David Joseph Katz before purchasing this course, since it’s one of the best ways to determine whether BAB&C|FE will be helpful for you.)

Are “Build a Blockchain & Cryptocurrency | Full-Stack Edition” reviews generally positive?

On the bottom of the BAB&C|FE page, you can read student reviews of the class.

Prior to August 20, 2025, there were 7,871 students enrolled, 1,110 reviews / ratings, and it was overall rated 4.5 out of 5.

Obviously, the more highly other students rate BAB&C|FE the better, but no matter what, keep an open mind when reading the reviews, since you might still like a course a great deal that other students dislike.

After all, everyone’s got their own opinion.

We recommend that you spend only a couple minutes scanning the BAB&C|FE reviews to get an overall sense of them. You don’t have to read each one!

Is David Joseph Katz responsive to student questions in the BAB&C|FE training?

You can see what other students have to say about this in their BAB&C|FE reviews.

But, our simple all time favorite way of gauging an instructor’s responsiveness is to simply email the instructor and see if or how they respond.

In this case, Udemy has a messaging system for students / anyone who has an account, and you can send David Joseph Katz a message through this system quite easily, even if you haven’t bought BAB&C|FE yet.

For example, you could say, “Hi, and I came across BAB&C|FE while looking at Development courses on Udemy. If I enroll in your training, would you mind if I asked you any questions along the way?”

If you use this approach, the response (or lack of response) from the professor will tell you everything.

Obviously, the quicker the response the better!

Are you comfortable going through the lessons in Build a Blockchain & Cryptocurrency | Full-Stack Edition on your own, online?

This is a big one, because Build a Blockchain & Cryptocurrency | Full-Stack Edition is an online course as opposed to a course that you physically take in a classroom.

Of course, you will need a good internet connection to have access to the course material and lessons, but beyond that, you also have to be comfortable being self motivated to some degree, being on your own, and not having any physical interaction with any of the other students taking Build a Blockchain & Cryptocurrency | Full-Stack Edition.

Yes, you will be able to interact with the students and the teacher, David Joseph Katz, online, but it’s a different kind of experience than what you’d get if you were interacting with them in person.

This is not a big deal to most people, but it might be something for you to consider if you feel like you do better taking classes in person rather than learning online.

Do the pros / benefits of BAB&C|FE make it worth your time?

Ideally, if you’ve gone through the evaluation steps above, you have a list of positive things about the Build a Blockchain & Cryptocurrency | Full-Stack Edition training that looks something like this:

• The purpose of BAB&C|FE can be clearly grasped and understood, and its lesson structure is clear, specific, and well organized
• David Joseph Katz is well qualified to teach this subject matter, has good teaching abilities, and is responsive to student questions
• Other BAB&C|FE students have great things to say about the program

Other benefits include:

• You get to go through BAB&C|FE at your own pace
• You join a community of 7,871 other students taking the course
• You get lifetime access to the training
• All updates to the training are free
• You have a 30 day money back guarantee

Even if there are some things that you don’t like about the program, so what?

The question is simply this: do you think that BAB&C|FE would be worth your time, even if there are some things that could be better about it?

Can you comfortably afford BAB&C|FE?

Can you comfortably afford the cost of Build a Blockchain & Cryptocurrency | Full-Stack Edition?

This is an important question to answer, because even if you think BAB&C|FE sounds like the greatest online class in the world, it’s still not worth taking if you can’t comfortably afford it!

Before August 20, 2025, the price was $12.99 before any Udemy discount, and you were able to pay with a credit card.

Keep in mind that this is a Udemy online course, and there’s a great chance that you can get a solid discount on BAB&C|FE with Udemy coupons / promo codes, especially with the strategies we provide for helping you find the best, most popular coupons available.

We’ll cover that in greater detail in the next section, because at the end of the day, its important that you can learn whatever you want to learn without getting into a lot of credit card debt.

How can you maximize your discount on Build a Blockchain & Cryptocurrency | Full-Stack Edition?

By far, the easiest way to get the best and biggest discount on this course is to use the Build a Blockchain & Cryptocurrency | Full-Stack Edition discount code link at the top of this page.

It will instantly give you the best coupon code we could find for David Joseph Katz’s online training.

We don’t believe there’s a bigger discount than the one we provided, but if for some reason you’d like to try find one, you can use the methods below to hunt for the best BAB&C|FE course coupons and promo codes you can find.

FYI, the methods below will help you not just with getting BAB&C|FE for a better price, but also with any other David Joseph Katz Udemy course that you’d like to get for cheaper.

How can Google help you get a BAB&C|FE discount?

To use this method, do a Google search for the BAB&C|FE training, but in your search query, be sure to add words like coupon code, promo code, deal, sale, discount, and Udemy.

For example, you might do a search for “Udemy Build a Blockchain & Cryptocurrency | Full-Stack Edition promo code” or “Build a Blockchain & Cryptocurrency | Full-Stack Edition udemy coupon codes” and see what turns up.

Similarly, you can use the same combination of search terms with David Joseph Katz’s name and see what happens.

For example, you might do a Google search for “David Joseph Katz Udemy coupons” or “David Joseph Katz course coupon codes” and see if that helps you.

However, in general, it’s far more powerful to do a search for deals and coupon codes with the actual training’s name, than with the instructor’s name.

So in this case, for example, prioritize searches for “Build a Blockchain & Cryptocurrency | Full-Stack Edition coupons” rather than “David Joseph Katz coupons”.

How can a Udemy sale get you BAB&C|FE for cheaper?

Every once in while, Udemy will do a sitewide sale where they offer all (or almost all) their courses at a discounted price. For example, one of the best sales is where every course is only $10 or $9.99.

So, if you’re interested in saving as much money as possible, you could wait and see if you can get BAB&C|FE for this cheaper Udemy sale price one day.

The problem is that these sales only occur sporadically, so you might be waiting for a while. Also, if David Joseph Katz decides not to participate in the site wide sale, then you won’t get a discount on BAB&C|FE, even though you could get a great discount on almost any other class at Udemy!

To understand this, think of there as being two different coupon categories for the BAB&C|FE course. Category one is an official Udemy coupon (which instructors can opt out of), while category two is a coupon offered directly by the instructor.

At the end of the day, it doesn’t matter what kind of a coupon tag you’re dealing with (for example, “officially from Udemy” or “officially from the instructor”), as long as long as as you’re dealing with active coupons that get you a better price.

How can you get a BAB&C|FE discount from David Joseph Katz?

If you’re really serious about getting “Build a Blockchain & Cryptocurrency | Full-Stack Edition” for the cheapest price possible, then perhaps one of the most powerful things you can do is get a coupon code straight from David Joseph Katz, instead of waiting for a Udemy sale.

To do this, you can use either the direct approach or an indirect approach to try to get your discount.

With the direct approach, the big idea is to simply get David Joseph Katz’s contact info in some way or another (whether it’s email, or Twitter, or whatever else).

Then you send a message saying something like “I’m interested in enrolling in Build a Blockchain & Cryptocurrency | Full-Stack Edition. Do you happen to currently have an active coupon code for it that I could use?” (And then, hopefully, you’ll get a reply with your discount code.)

On the other hand, with the indirect approach, you join David Joseph Katz’s mailing list, if you can find it, and then you hope that at some time BAB&C|FE will be promoted to you at a discount.

By far, the more powerful approach is the direct approach, because it tends to get results faster. But you can experiment with the indirect approach and see if it works for you.

Can you get BAB&C|FE for free?

Of course, the best possible price for the BAB&C|FE training is free! As in, you pay no money whatsoever.

And guess what? Sometimes Udemy instructors provide coupon codes that enable students to take their courses for free. So, perhaps it’s possible that David Joseph Katz has done this.

Basically, if you’re trying to get this program for free, you will want to search for the course’s name along with other words like free coupon, or 100 off coupon.

For example, you might do a google search for “Build a Blockchain & Cryptocurrency | Full-Stack Edition free coupon” or “Build a Blockchain & Cryptocurrency | Full-Stack Edition 100 off coupon” and see what happens.

But keep this in mind: often, Udemy teachers will offer a free coupon for their course when it first opens to get some publicity and reviews. And then, after a few days, they’ll make the coupon expired.

So even David Joseph Katz has offered free coupons for BAB&C|FE in the past, the odds are likely they will all be currently expired. This is a common pattern that we have found.

What about a BAB&C|FE free download?

It’s important to understand that there’s a difference between getting full access to the BAB&C|FE training for free legally with a free coupon code vs. finding a way to download BAB&C|FE illegally.

If you really want to go the download route, you can do a google search for something like “Build a Blockchain & Cryptocurrency | Full-Stack Edition download”.

And if that doesn’t get you the results you want, you can add the word “free” to your search.

For example, perhaps you could do a google search for “Build a Blockchain & Cryptocurrency | Full-Stack Edition free download”.

However, even if you get some results from these searches, we do not recommend that you take this course of action.

First of all, there are some shady sites out there that could be trying to infect your computer.

Second, David Joseph Katz created this course and deserves monetary compensation for it.

And third, if you go the free download route, you’ll be missing out on a lot of value, because you won’t be able to ask the instructor questions or interact with the other 7,871 students enrolled in the program.

Can you get a refund on Build a Blockchain & Cryptocurrency | Full-Stack Edition if you don’t like it?

Let’s say that you used our tips above, and you were able to buy the BAB&C|FE training at a fantastic discounted price. So at this point, you’re super excited.

Then, you actually dive into David Joseph Katz’s course, and you discover that it just isn’t for you for whatever reason.

And now you’re super bummed, because you feel like it wasn’t money well spent.

Well, guess what?

Udemy offers a rock solid 30 day money back guarantee on all their courses, so you can get a refund on BAB&C|FE no matter what. And this means there is absolutely no risk.

Indeed, even if you left a super negative, critical review on the BAB&C|FE training, and then asked for your money back, you’d get a refund. For better or worse, there’s nothing David Joseph Katz could do about it, since it is simply Udemy policy.

To sum it up: yes, you can get a full refund, so at the end of the day, don’t worry about the possibility of purchasing BAB&C|FE and not liking it, since you can always get your money back.

What is OCP’s overall rating of Build a Blockchain & Cryptocurrency | Full-Stack Edition?

During this BAB&C|FE review, you’ve learned about some of the unusual ways we like to evaluate courses, such as with The 30 Second Test and The 15 Second Bio Test.

So our overall review process is perhaps a little unusual and different from other reviews out there. Keep this in mind when you consider the overall rating / score that we have given this course.

Anyway, after taking a look at the BAB&C|FE training, the instructor, David Joseph Katz, and reading what other students have said about this program, we give it an overall rating of 4.6 out of 5.

Ultimately, though, what matters most is what you would rate it based on the same criteria.

Why use RJWD-TEB as an abbreviation of the course name?

In any case, the more familiar you are with David Joseph Katz’s teaching methods, and the more you enjoy them, the more likely it is that React JS Web Development – The Essentials Bootcamp will be a good fit for you.

(P.S.: We strongly encourage you to seek out some free instruction from David Joseph Katz before purchasing this course, since it’s one of the best ways to determine whether RJWD-TEB will be helpful for you.)

Are “React JS Web Development – The Essentials Bootcamp” reviews generally positive?

On the bottom of the RJWD-TEB page, you can read student reviews of the class.

Prior to August 20, 2025, there were 10,807 students enrolled, 4,189 reviews / ratings, and it was overall rated 4.4 out of 5.

Obviously, the more highly other students rate RJWD-TEB the better, but no matter what, keep an open mind when reading the reviews, since you might still like a course a great deal that other students dislike.

After all, everyone’s got their own opinion.

We recommend that you spend only a couple minutes scanning the RJWD-TEB reviews to get an overall sense of them. You don’t have to read each one!

Is David Joseph Katz responsive to student questions in the RJWD-TEB training?

You can see what other students have to say about this in their RJWD-TEB reviews.

But, our simple all time favorite way of gauging an instructor’s responsiveness is to simply email the instructor and see if or how they respond.

In this case, Udemy has a messaging system for students / anyone who has an account, and you can send David Joseph Katz a message through this system quite easily, even if you haven’t bought RJWD-TEB yet.

For example, you could say, “Hi, and I came across RJWD-TEB while looking at Development courses on Udemy. If I enroll in your training, would you mind if I asked you any questions along the way?”

If you use this approach, the response (or lack of response) from the professor will tell you everything.

Obviously, the quicker the response the better!

Are you comfortable going through the lessons in React JS Web Development – The Essentials Bootcamp on your own, online?

This is a big one, because React JS Web Development – The Essentials Bootcamp is an online course as opposed to a course that you physically take in a classroom.

Of course, you will need a good internet connection to have access to the course material and lessons, but beyond that, you also have to be comfortable being self motivated to some degree, being on your own, and not having any physical interaction with any of the other students taking React JS Web Development – The Essentials Bootcamp.

Yes, you will be able to interact with the students and the teacher, David Joseph Katz, online, but it’s a different kind of experience than what you’d get if you were interacting with them in person.

This is not a big deal to most people, but it might be something for you to consider if you feel like you do better taking classes in person rather than learning online.

Do the pros / benefits of RJWD-TEB make it worth your time?

Ideally, if you’ve gone through the evaluation steps above, you have a list of positive things about the React JS Web Development – The Essentials Bootcamp training that looks something like this:

• The purpose of RJWD-TEB can be clearly grasped and understood, and its lesson structure is clear, specific, and well organized
• David Joseph Katz is well qualified to teach this subject matter, has good teaching abilities, and is responsive to student questions
• Other RJWD-TEB students have great things to say about the program

Other benefits include:

• You get to go through RJWD-TEB at your own pace
• You join a community of 10,807 other students taking the course
• You get lifetime access to the training
• All updates to the training are free
• You have a 30 day money back guarantee

Even if there are some things that you don’t like about the program, so what?

The question is simply this: do you think that RJWD-TEB would be worth your time, even if there are some things that could be better about it?

Can you comfortably afford RJWD-TEB?

Can you comfortably afford the cost of React JS Web Development – The Essentials Bootcamp?

This is an important question to answer, because even if you think RJWD-TEB sounds like the greatest online class in the world, it’s still not worth taking if you can’t comfortably afford it!

Before August 20, 2025, the price was $12.99 before any Udemy discount, and you were able to pay with a credit card.

Keep in mind that this is a Udemy online course, and there’s a great chance that you can get a solid discount on RJWD-TEB with Udemy coupons / promo codes, especially with the strategies we provide for helping you find the best, most popular coupons available.

We’ll cover that in greater detail in the next section, because at the end of the day, its important that you can learn whatever you want to learn without getting into a lot of credit card debt.

How can you maximize your discount on React JS Web Development – The Essentials Bootcamp?

By far, the easiest way to get the best and biggest discount on this course is to use the React JS Web Development – The Essentials Bootcamp discount code link at the top of this page.

It will instantly give you the best coupon code we could find for David Joseph Katz’s online training.

We don’t believe there’s a bigger discount than the one we provided, but if for some reason you’d like to try find one, you can use the methods below to hunt for the best RJWD-TEB course coupons and promo codes you can find.

FYI, the methods below will help you not just with getting RJWD-TEB for a better price, but also with any other David Joseph Katz Udemy course that you’d like to get for cheaper.

How can Google help you get a RJWD-TEB discount?

To use this method, do a Google search for the RJWD-TEB training, but in your search query, be sure to add words like coupon code, promo code, deal, sale, discount, and Udemy.

For example, you might do a search for “Udemy React JS Web Development – The Essentials Bootcamp promo code” or “React JS Web Development – The Essentials Bootcamp udemy coupon codes” and see what turns up.

Similarly, you can use the same combination of search terms with David Joseph Katz’s name and see what happens.

For example, you might do a Google search for “David Joseph Katz Udemy coupons” or “David Joseph Katz course coupon codes” and see if that helps you.

However, in general, it’s far more powerful to do a search for deals and coupon codes with the actual training’s name, than with the instructor’s name.

So in this case, for example, prioritize searches for “React JS Web Development – The Essentials Bootcamp coupons” rather than “David Joseph Katz coupons”.

How can a Udemy sale get you RJWD-TEB for cheaper?

Every once in while, Udemy will do a sitewide sale where they offer all (or almost all) their courses at a discounted price. For example, one of the best sales is where every course is only $10 or $9.99.

So, if you’re interested in saving as much money as possible, you could wait and see if you can get RJWD-TEB for this cheaper Udemy sale price one day.

The problem is that these sales only occur sporadically, so you might be waiting for a while. Also, if David Joseph Katz decides not to participate in the site wide sale, then you won’t get a discount on RJWD-TEB, even though you could get a great discount on almost any other class at Udemy!

To understand this, think of there as being two different coupon categories for the RJWD-TEB course. Category one is an official Udemy coupon (which instructors can opt out of), while category two is a coupon offered directly by the instructor.

At the end of the day, it doesn’t matter what kind of a coupon tag you’re dealing with (for example, “officially from Udemy” or “officially from the instructor”), as long as long as as you’re dealing with active coupons that get you a better price.

How can you get a RJWD-TEB discount from David Joseph Katz?

If you’re really serious about getting “React JS Web Development – The Essentials Bootcamp” for the cheapest price possible, then perhaps one of the most powerful things you can do is get a coupon code straight from David Joseph Katz, instead of waiting for a Udemy sale.

To do this, you can use either the direct approach or an indirect approach to try to get your discount.

With the direct approach, the big idea is to simply get David Joseph Katz’s contact info in some way or another (whether it’s email, or Twitter, or whatever else).

Then you send a message saying something like “I’m interested in enrolling in React JS Web Development – The Essentials Bootcamp. Do you happen to currently have an active coupon code for it that I could use?” (And then, hopefully, you’ll get a reply with your discount code.)

On the other hand, with the indirect approach, you join David Joseph Katz’s mailing list, if you can find it, and then you hope that at some time RJWD-TEB will be promoted to you at a discount.

By far, the more powerful approach is the direct approach, because it tends to get results faster. But you can experiment with the indirect approach and see if it works for you.

Can you get RJWD-TEB for free?

Of course, the best possible price for the RJWD-TEB training is free! As in, you pay no money whatsoever.

And guess what? Sometimes Udemy instructors provide coupon codes that enable students to take their courses for free. So, perhaps it’s possible that David Joseph Katz has done this.

Basically, if you’re trying to get this program for free, you will want to search for the course’s name along with other words like free coupon, or 100 off coupon.

For example, you might do a google search for “React JS Web Development – The Essentials Bootcamp free coupon” or “React JS Web Development – The Essentials Bootcamp 100 off coupon” and see what happens.

But keep this in mind: often, Udemy teachers will offer a free coupon for their course when it first opens to get some publicity and reviews. And then, after a few days, they’ll make the coupon expired.

So even David Joseph Katz has offered free coupons for RJWD-TEB in the past, the odds are likely they will all be currently expired. This is a common pattern that we have found.

What about a RJWD-TEB free download?

It’s important to understand that there’s a difference between getting full access to the RJWD-TEB training for free legally with a free coupon code vs. finding a way to download RJWD-TEB illegally.

If you really want to go the download route, you can do a google search for something like “React JS Web Development – The Essentials Bootcamp download”.

And if that doesn’t get you the results you want, you can add the word “free” to your search.

For example, perhaps you could do a google search for “React JS Web Development – The Essentials Bootcamp free download”.

However, even if you get some results from these searches, we do not recommend that you take this course of action.

First of all, there are some shady sites out there that could be trying to infect your computer.

Second, David Joseph Katz created this course and deserves monetary compensation for it.

And third, if you go the free download route, you’ll be missing out on a lot of value, because you won’t be able to ask the instructor questions or interact with the other 10,807 students enrolled in the program.

Can you get a refund on React JS Web Development – The Essentials Bootcamp if you don’t like it?

Let’s say that you used our tips above, and you were able to buy the RJWD-TEB training at a fantastic discounted price. So at this point, you’re super excited.

Then, you actually dive into David Joseph Katz’s course, and you discover that it just isn’t for you for whatever reason.

And now you’re super bummed, because you feel like it wasn’t money well spent.

Well, guess what?

Udemy offers a rock solid 30 day money back guarantee on all their courses, so you can get a refund on RJWD-TEB no matter what. And this means there is absolutely no risk.

Indeed, even if you left a super negative, critical review on the RJWD-TEB training, and then asked for your money back, you’d get a refund. For better or worse, there’s nothing David Joseph Katz could do about it, since it is simply Udemy policy.

To sum it up: yes, you can get a full refund, so at the end of the day, don’t worry about the possibility of purchasing RJWD-TEB and not liking it, since you can always get your money back.

What is OCP’s overall rating of React JS Web Development – The Essentials Bootcamp?

During this RJWD-TEB review, you’ve learned about some of the unusual ways we like to evaluate courses, such as with The 30 Second Test and The 15 Second Bio Test.

So our overall review process is perhaps a little unusual and different from other reviews out there. Keep this in mind when you consider the overall rating / score that we have given this course.

Anyway, after taking a look at the RJWD-TEB training, the instructor, David Joseph Katz, and reading what other students have said about this program, we give it an overall rating of 4.8 out of 5.

Ultimately, though, what matters most is what you would rate it based on the same criteria.

Vue JS 2.0 – Mastering Web Apps review for 2025

In our review of this course, we try to help you answer all of your most important questions about Vue JS 2.0 – Mastering Web Apps as quickly and efficiently as possible, so that you can determine whether this online education training is worth your time and money.

Feel free to jump to whatever question you want answered the most.

Here’s what you’ll learn:

Why use VJ2-MWA as an abbreviation of the course name?

During our Vue JS 2.0 – Mastering Web Apps course review, you might sometimes see us refer to it as VJ2-MWA for the following 2 reasons:

1. We created the acronym by taking the first letter of every word (which was very ingenious and innovative, we know)
2. We’re lazy and VJ2-MWA is simpler and easier for reviewing purposes

The full course name is 31 characters long, including blanks, while VJ2-MWA is 7 characters long.

You do the math.

Okay, we’ll do the math. We’re saving 24 characters every time we use VJ2-MWA.

So, just a heads up that we’ll be using this abbreviation sometimes, so you’re not left scratching your head and wondering what the heck we’re talking about whenever we refer to VJ2-MWA throughout the remainder of this review.

Is the Vue JS 2.0 – Mastering Web Apps course for you?

To determine whether David Joseph Katz’s Udemy course is a good fit for you or not, ask yourself the following questions down below.

The more you answer “yes” to each question, the more likely it is that you’ll like this course.

Can you understand what David Joseph Katz’s course is about in 30 seconds or less?

Hopefully, you can easily grasp in 10 seconds or less what this online course is about simply by taking a look at the title that David Joseph Katz chose for the course, “Vue JS 2.0 – Mastering Web Apps”, as well as its subtitle: “Create the VueJS 2.0 apps you always wanted. Build 5 apps, learn development secrets, VueRouter, Vuex, & more!”.

This combo of title and subtitle should be enough to communicate the purpose of the training if David Joseph Katz is a good, clear communicator (which, of course, you want in a teacher).

In our opinion, if you still don’t know what VJ2-MWA is about after looking at these two things, then this is a red flag, and you might be better off not taking this class.

Among other things, it means David Joseph Katz hasn’t clearly and accurately conveyed what the course is about and might not be the best teacher for you.

For similar reasons, it’s important that you’re able to clearly understand what Vue JS 2.0 – Mastering Web Apps is all about from the first few lines of the course description.

So take just a few seconds to read the opening lines down below and see what you think of them. 

Opening lines of David Joseph Katz’s official description of VJ2-MWA

Become an in-demand software engineer by taking this tutorial on Vue Js. As one of the fastest growing frameworks for web development, learning Vue is a must. Simply put, understanding Vue will open doors and jobs for you.

This project-based course will have you coding right away. By building five carefully thought-out example applications, you will sharpen your skills in modern web development.

First, learn the essentials of Vue 2.0 by going through the main concepts and syntax. Then, build your first single-page app with Vue. Second, create an application that handles HTTP Web Requests in Vue and uses a public API. Extend upon this application next, learning VueRouter for multi-page applications. Fourth, build an application that works with Vuex to manage data. Finally, cap it all off by building an app with full authentication and a real-time database.

(Read more about this course on the official course page.)

Does VJ2-MWA pass the 30 Seconds Test?

You can read a lot more about Vue JS 2.0 – Mastering Web Apps on the official course page on Udemy, but the point is this: are the title, subtitle, and just the first few lines of the description enough to help you understand what the course is about?

If so, David Joseph Katz has done a good job and can be considered more trustworthy and a good communicator, which are important qualities for any teacher.

And, if not, maybe you’re better off looking at other Development classes that are more clearly defined and more tailored to your specific interests.

Did Vue JS 2.0 – Mastering Web Apps appeal to you in 30 seconds or less?

Now that you’ve done the 30 Second Test with VJ2-MWA above, what is your gut reaction to this Development course with only the basic information of its title, subtitle, and the first few opening lines of its official course summary?

Did David Joseph Katz do a good job conveying its subject matter, and did it immediately get your attention and appeal to you?

If so, David Joseph Katz’s online course is certainly worth considering some more.

But if not, perhaps it’s in your best interest to consider some other Development courses instead, because clear communication and being able to hook and maintain your interest are two very important qualities for your online learning success.

Does David Joseph Katz sound like a course instructor you’d like to learn from?

You’ve already learned how to use The 30 Second Test to make a quick evaluation of whether the VJ2-MWA course is worth taking.

We have a similar 15 Second Bio Test where you read only the first few lines of an instructor’s background — in this case, David Joseph Katz’s background — and then you make a quick, snap judgment as to whether you think the instructor would be ideal for you.

There is no right or wrong answer. It’s just about going with your gut instinct. What might appeal to one potential student might alienate another, and vice versa.

(FYI, all Udemy instructors, including David Joseph Katz, have a Udemy profile on their course page, so you can easily check for a bio and background on the Udemy website that way. We’re only including the first few lines of the bio down below for The 15 Second Bio Test).

Opening lines from David Joseph Katz’s Udemy bio

David is a software engineer at Zendesk, with a Bachelor of Computer Science from the University of San Francisco.

(Learn more about this instructor on the official course page.)

What did you think about David Joseph Katz after reading just the first few lines of the bio above?

After reading just the first few lines about David Joseph Katz, did it make you more or less interested in taking the VJ2-MWA course?

And did it make you feel like David Joseph Katz was more or less credible and qualified to teach Vue JS 2.0 – Mastering Web Apps?

Finally, overall, did you feel like you’d receive the proper training from the instructor of this Development course?

As always, we encourage you to listen to your gut instinct, which is different for every student.

Are the VJ2-MWA lessons clear, specific, and organized well?

Part of the (good) problem with Udemy’s online courses, such as the Vue JS 2.0 – Mastering Web Apps course, is that the instructors are constantly updating them, including adding and renaming lessons.

So it makes no sense whatsoever for us to list out all the modules and lessons in the VJ2-MWA course here, because you can just as easily go to the Udemy course page and get all the up to date course structure as of right now.

We do, however, have some tips about reviewing David Joseph Katz’s course structure, so that you can get a better sense of whether this program is worth your time or not.

In a nutshell, you want to scan the the titles of the different sections and lessons of the course, and verify that they are clearly relevant to the course’s name, Vue JS 2.0 – Mastering Web Apps, as well as the course’s subtitle, Create the VueJS 2.0 apps you always wanted. Build 5 apps, learn development secrets, VueRouter, Vuex, & more!.

If the section names and lessons are clear, specific, and relevant, then it’s a good sign that VJ2-MWA is potentially a good, useful course for you, and you can have more confidence in David Joseph Katz’s teaching abilities and lesson planning.

On the other hand, if the module names are confusing, vague, or irrelevant, then this is a red flag, which might indicate that the program is worth skipping.

Have you taken some free lessons from David Joseph Katz that you enjoyed?

Have you already learned something from David Joseph Katz that you valued or enjoyed?

For example, does the Vue JS 2.0 – Mastering Web Apps training have some free lessons that you can try? (Almost all Udemy instructors will give you at least one or two lessons for free to help you make a better, more informed decision before enrolling in their course.)

But if you weren’t able to get any VJ2-MWA lessons for free, have you perhaps watched a YouTube video by David Joseph Katz, or perhaps come across this instructor’s thoughts on Quora, Facebook, LinkedIn, Github, Reddit, or some other platform?

Or have you perhaps even taken one of David Joseph Katz’s free courses or free webinars? (Many online teachers offer these freebies, which is a great way to get to know them and evaluate their teaching methods before buying one of their courses.)

In any case, the more familiar you are with David Joseph Katz’s teaching methods, and the more you enjoy them, the more likely it is that Vue JS 2.0 – Mastering Web Apps will be a good fit for you.

(P.S.: We strongly encourage you to seek out some free instruction from David Joseph Katz before purchasing this course, since it’s one of the best ways to determine whether VJ2-MWA will be helpful for you.)

Are “Vue JS 2.0 – Mastering Web Apps” reviews generally positive?

On the bottom of the VJ2-MWA page, you can read student reviews of the class.

Prior to August 20, 2025, there were 4,827 students enrolled, 1,983 reviews / ratings, and it was overall rated 4.2 out of 5.

Obviously, the more highly other students rate VJ2-MWA the better, but no matter what, keep an open mind when reading the reviews, since you might still like a course a great deal that other students dislike.

After all, everyone’s got their own opinion.

We recommend that you spend only a couple minutes scanning the VJ2-MWA reviews to get an overall sense of them. You don’t have to read each one!

Is David Joseph Katz responsive to student questions in the VJ2-MWA training?

You can see what other students have to say about this in their VJ2-MWA reviews.

But, our simple all time favorite way of gauging an instructor’s responsiveness is to simply email the instructor and see if or how they respond.

In this case, Udemy has a messaging system for students / anyone who has an account, and you can send David Joseph Katz a message through this system quite easily, even if you haven’t bought VJ2-MWA yet.

For example, you could say, “Hi, and I came across VJ2-MWA while looking at Development courses on Udemy. If I enroll in your training, would you mind if I asked you any questions along the way?”

If you use this approach, the response (or lack of response) from the professor will tell you everything.

Obviously, the quicker the response the better!

Are you comfortable going through the lessons in Vue JS 2.0 – Mastering Web Apps on your own, online?

This is a big one, because Vue JS 2.0 – Mastering Web Apps is an online course as opposed to a course that you physically take in a classroom.

Of course, you will need a good internet connection to have access to the course material and lessons, but beyond that, you also have to be comfortable being self motivated to some degree, being on your own, and not having any physical interaction with any of the other students taking Vue JS 2.0 – Mastering Web Apps.

Yes, you will be able to interact with the students and the teacher, David Joseph Katz, online, but it’s a different kind of experience than what you’d get if you were interacting with them in person.

This is not a big deal to most people, but it might be something for you to consider if you feel like you do better taking classes in person rather than learning online.

Do the pros / benefits of VJ2-MWA make it worth your time?

Ideally, if you’ve gone through the evaluation steps above, you have a list of positive things about the Vue JS 2.0 – Mastering Web Apps training that looks something like this:

• The purpose of VJ2-MWA can be clearly grasped and understood, and its lesson structure is clear, specific, and well organized

• You join a community of 4,827 other students taking the course
• You get lifetime access to the training
• All updates to the training are free
• You have a 30 day money back guarantee

Even if there are some things that you don’t like about the program, so what?

The question is simply this: do you think that VJ2-MWA would be worth your time, even if there are some things that could be better about it?

Can you comfortably afford VJ2-MWA?

Can you comfortably afford the cost of Vue JS 2.0 – Mastering Web Apps?

This is an important question to answer, because even if you think VJ2-MWA sounds like the greatest online class in the world, it’s still not worth taking if you can’t comfortably afford it!

Before August 20, 2025, the price was $12.99 before any Udemy discount, and you were able to pay with a credit card.

Keep in mind that this is a Udemy online course, and there’s a great chance that you can get a solid discount on VJ2-MWA with Udemy coupons / promo codes, especially with the strategies we provide for helping you find the best, most popular coupons available.

FYI, the methods below will help you not just with getting VJ2-MWA for a better price, but also with any other David Joseph Katz Udemy course that you’d like to get for cheaper.

How can Google help you get a VJ2-MWA discount?

To use this method, do a Google search for the VJ2-MWA training, but in your search query, be sure to add words like coupon code, promo code, deal, sale, discount, and Udemy.

For example, you might do a search for “Udemy Vue JS 2.0 – Mastering Web Apps promo code” or “Vue JS 2.0 – Mastering Web Apps udemy coupon codes” and see what turns up.

Similarly, you can use the same combination of search terms with David Joseph Katz’s name and see what happens.

For example, you might do a Google search for “David Joseph Katz Udemy coupons” or “David Joseph Katz course coupon codes” and see if that helps you.

However, in general, it’s far more powerful to do a search for deals and coupon codes with the actual training’s name, than with the instructor’s name.

So in this case, for example, prioritize searches for “Vue JS 2.0 – Mastering Web Apps coupons” rather than “David Joseph Katz coupons”.

How can a Udemy sale get you VJ2-MWA for cheaper?

Every once in while, Udemy will do a sitewide sale where they offer all (or almost all) their courses at a discounted price. For example, one of the best sales is where every course is only $10 or $9.99.

So, if you’re interested in saving as much money as possible, you could wait and see if you can get VJ2-MWA for this cheaper Udemy sale price one day.

The problem is that these sales only occur sporadically, so you might be waiting for a while. Also, if David Joseph Katz decides not to participate in the site wide sale, then you won’t get a discount on VJ2-MWA, even though you could get a great discount on almost any other class at Udemy!

To understand this, think of there as being two different coupon categories for the VJ2-MWA course. Category one is an official Udemy coupon (which instructors can opt out of), while category two is a coupon offered directly by the instructor.

At the end of the day, it doesn’t matter what kind of a coupon tag you’re dealing with (for example, “officially from Udemy” or “officially from the instructor”), as long as long as as you’re dealing with active coupons that get you a better price.

How can you get a VJ2-MWA discount from David Joseph Katz?

If you’re really serious about getting “Vue JS 2.0 – Mastering Web Apps” for the cheapest price possible, then perhaps one of the most powerful things you can do is get a coupon code straight from David Joseph Katz, instead of waiting for a Udemy sale.

To do this, you can use either the direct approach or an indirect approach to try to get your discount.

With the direct approach, the big idea is to simply get David Joseph Katz’s contact info in some way or another (whether it’s email, or Twitter, or whatever else).

Then you send a message saying something like “I’m interested in enrolling in Vue JS 2.0 – Mastering Web Apps. Do you happen to currently have an active coupon code for it that I could use?” (And then, hopefully, you’ll get a reply with your discount code.)

On the other hand, with the indirect approach, you join David Joseph Katz’s mailing list, if you can find it, and then you hope that at some time VJ2-MWA will be promoted to you at a discount.

By far, the more powerful approach is the direct approach, because it tends to get results faster. But you can experiment with the indirect approach and see if it works for you.

Can you get VJ2-MWA for free?

Of course, the best possible price for the VJ2-MWA training is free! As in, you pay no money whatsoever.

And guess what? Sometimes Udemy instructors provide coupon codes that enable students to take their courses for free. So, perhaps it’s possible that David Joseph Katz has done this.

Basically, if you’re trying to get this program for free, you will want to search for the course’s name along with other words like free coupon, or 100 off coupon.

For example, you might do a google search for “Vue JS 2.0 – Mastering Web Apps free coupon” or “Vue JS 2.0 – Mastering Web Apps 100 off coupon” and see what happens.

But keep this in mind: often, Udemy teachers will offer a free coupon for their course when it first opens to get some publicity and reviews. And then, after a few days, they’ll make the coupon expired.

So even David Joseph Katz has offered free coupons for VJ2-MWA in the past, the odds are likely they will all be currently expired. This is a common pattern that we have found.

What about a VJ2-MWA free download?

It’s important to understand that there’s a difference between getting full access to the VJ2-MWA training for free legally with a free coupon code vs. finding a way to download VJ2-MWA illegally.

If you really want to go the download route, you can do a google search for something like “Vue JS 2.0 – Mastering Web Apps download”.

And if that doesn’t get you the results you want, you can add the word “free” to your search.

For example, perhaps you could do a google search for “Vue JS 2.0 – Mastering Web Apps free download”.

However, even if you get some results from these searches, we do not recommend that you take this course of action.

First of all, there are some shady sites out there that could be trying to infect your computer.

Second, David Joseph Katz created this course and deserves monetary compensation for it.

And third, if you go the free download route, you’ll be missing out on a lot of value, because you won’t be able to ask the instructor questions or interact with the other 4,827 students enrolled in the program.

Can you get a refund on Vue JS 2.0 – Mastering Web Apps if you don’t like it?

Let’s say that you used our tips above, and you were able to buy the VJ2-MWA training at a fantastic discounted price. So at this point, you’re super excited.

Then, you actually dive into David Joseph Katz’s course, and you discover that it just isn’t for you for whatever reason.

And now you’re super bummed, because you feel like it wasn’t money well spent.

Well, guess what?

Udemy offers a rock solid 30 day money back guarantee on all their courses, so you can get a refund on VJ2-MWA no matter what. And this means there is absolutely no risk.

Indeed, even if you left a super negative, critical review on the VJ2-MWA training, and then asked for your money back, you’d get a refund. For better or worse, there’s nothing David Joseph Katz could do about it, since it is simply Udemy policy.

To sum it up: yes, you can get a full refund, so at the end of the day, don’t worry about the possibility of purchasing VJ2-MWA and not liking it, since you can always get your money back.

What is OCP’s overall rating of Vue JS 2.0 – Mastering Web Apps?

During this VJ2-MWA review, you’ve learned about some of the unusual ways we like to evaluate courses, such as with The 30 Second Test and The 15 Second Bio Test.

So our overall review process is perhaps a little unusual and different from other reviews out there. Keep this in mind when you consider the overall rating / score that we have given this course.

Anyway, after taking a look at the VJ2-MWA training, the instructor, David Joseph Katz, and reading what other students have said about this program, we give it an overall rating of 4.5 out of 5.

Ultimately, though, what matters most is what you would rate it based on the same criteria.

React – Mastering Test Driven Development review for 2025

In our review of this course, we try to help you answer all of your most important questions about React – Mastering Test Driven Development as quickly and efficiently as possible, so that you can determine whether this online education training is worth your time and money.

Feel free to jump to whatever question you want answered the most.

Here’s what you’ll learn:

Why use R-MTDD as an abbreviation of the course name?

During our React – Mastering Test Driven Development course review, you might sometimes see us refer to it as R-MTDD for the following 2 reasons:

1. We created the acronym by taking the first letter of every word (which was very ingenious and innovative, we know)
2. We’re lazy and R-MTDD is simpler and easier for reviewing purposes

The full course name is 41 characters long, including blanks, while R-MTDD is 6 characters long.

You do the math.

Okay, we’ll do the math. We’re saving 35 characters every time we use R-MTDD.

So, just a heads up that we’ll be using this abbreviation sometimes, so you’re not left scratching your head and wondering what the heck we’re talking about whenever we refer to R-MTDD throughout the remainder of this review.

Is the React – Mastering Test Driven Development course for you?

To determine whether David Joseph Katz’s Udemy course is a good fit for you or not, ask yourself the following questions down below.

The more you answer “yes” to each question, the more likely it is that you’ll like this course.

Can you understand what David Joseph Katz’s course is about in 30 seconds or less?

Hopefully, you can easily grasp in 10 seconds or less what this online course is about simply by taking a look at the title that David Joseph Katz chose for the course, “React – Mastering Test Driven Development”, as well as its subtitle: “Upgrade your React skills with Test Driven Development! Jest, Enzyme, Redux, middleware, ES6, & more!”.

This combo of title and subtitle should be enough to communicate the purpose of the training if David Joseph Katz is a good, clear communicator (which, of course, you want in a teacher).

In our opinion, if you still don’t know what R-MTDD is about after looking at these two things, then this is a red flag, and you might be better off not taking this class.

Among other things, it means David Joseph Katz hasn’t clearly and accurately conveyed what the course is about and might not be the best teacher for you.

For similar reasons, it’s important that you’re able to clearly understand what React – Mastering Test Driven Development is all about from the first few lines of the course description.

So take just a few seconds to read the opening lines down below and see what you think of them. 

Opening lines of David Joseph Katz’s official description of R-MTDD

Become an in demand software engineer by taking this course on React as well as Test and Behavior Driven Development. As arguably the most popular web development framework today, learning React along with testing is a must. Knowing how to create React applications with thorough tests will open doors and jobs for you.

In this project-based course, you’ll learn how to build React and Redux applications in a test and behavior driven development approach. You’ll discover testing practices widely used in the industry today. And you’ll find out how to use notable testing libraries like Jest and Enzyme.

You will skyrocket to the top of the talent pool because you can write tests. Coding the apps is only half of the process. Knowing how to write tests is the other crucial skill looked for by top software companies like Google, Facebook, Microsoft, and more.

(Read more about this course on the official course page.)

Does R-MTDD pass the 30 Seconds Test?

You can read a lot more about React – Mastering Test Driven Development on the official course page on Udemy, but the point is this: are the title, subtitle, and just the first few lines of the description enough to help you understand what the course is about?

If so, David Joseph Katz has done a good job and can be considered more trustworthy and a good communicator, which are important qualities for any teacher.

And, if not, maybe you’re better off looking at other Development classes that are more clearly defined and more tailored to your specific interests.

Did React – Mastering Test Driven Development appeal to you in 30 seconds or less?

Now that you’ve done the 30 Second Test with R-MTDD above, what is your gut reaction to this Development course with only the basic information of its title, subtitle, and the first few opening lines of its official course summary?

Did David Joseph Katz do a good job conveying its subject matter, and did it immediately get your attention and appeal to you?

If so, David Joseph Katz’s online course is certainly worth considering some more.

But if not, perhaps it’s in your best interest to consider some other Development courses instead, because clear communication and being able to hook and maintain your interest are two very important qualities for your online learning success.

Does David Joseph Katz sound like a course instructor you’d like to learn from?

You’ve already learned how to use The 30 Second Test to make a quick evaluation of whether the R-MTDD course is worth taking.

We have a similar 15 Second Bio Test where you read only the first few lines of an instructor’s background — in this case, David Joseph Katz’s background — and then you make a quick, snap judgment as to whether you think the instructor would be ideal for you.

There is no right or wrong answer. It’s just about going with your gut instinct. What might appeal to one potential student might alienate another, and vice versa.

(FYI, all Udemy instructors, including David Joseph Katz, have a Udemy profile on their course page, so you can easily check for a bio and background on the Udemy website that way. We’re only including the first few lines of the bio down below for The 15 Second Bio Test).

Opening lines from David Joseph Katz’s Udemy bio

David is a software engineer at Zendesk, with a Bachelor of Computer Science from the University of San Francisco.

(Learn more about this instructor on the official course page.)

What did you think about David Joseph Katz after reading just the first few lines of the bio above?

After reading just the first few lines about David Joseph Katz, did it make you more or less interested in taking the R-MTDD course?

And did it make you feel like David Joseph Katz was more or less credible and qualified to teach React – Mastering Test Driven Development?

Finally, overall, did you feel like you’d receive the proper training from the instructor of this Development course?

As always, we encourage you to listen to your gut instinct, which is different for every student.

Are the R-MTDD lessons clear, specific, and organized well?

Part of the (good) problem with Udemy’s online courses, such as the React – Mastering Test Driven Development course, is that the instructors are constantly updating them, including adding and renaming lessons.

So it makes no sense whatsoever for us to list out all the modules and lessons in the R-MTDD course here, because you can just as easily go to the Udemy course page and get all the up to date course structure as of right now.

We do, however, have some tips about reviewing David Joseph Katz’s course structure, so that you can get a better sense of whether this program is worth your time or not.

In a nutshell, you want to scan the the titles of the different sections and lessons of the course, and verify that they are clearly relevant to the course’s name, React – Mastering Test Driven Development, as well as the course’s subtitle, Upgrade your React skills with Test Driven Development! Jest, Enzyme, Redux, middleware, ES6, & more!.

If the section names and lessons are clear, specific, and relevant, then it’s a good sign that R-MTDD is potentially a good, useful course for you, and you can have more confidence in David Joseph Katz’s teaching abilities and lesson planning.

On the other hand, if the module names are confusing, vague, or irrelevant, then this is a red flag, which might indicate that the program is worth skipping.

Have you taken some free lessons from David Joseph Katz that you enjoyed?

Have you already learned something from David Joseph Katz that you valued or enjoyed?

For example, does the React – Mastering Test Driven Development training have some free lessons that you can try? (Almost all Udemy instructors will give you at least one or two lessons for free to help you make a better, more informed decision before enrolling in their course.)

But if you weren’t able to get any R-MTDD lessons for free, have you perhaps watched a YouTube video by David Joseph Katz, or perhaps come across this instructor’s thoughts on Quora, Facebook, LinkedIn, Github, Reddit, or some other platform?

Or have you perhaps even taken one of David Joseph Katz’s free courses or free webinars? (Many online teachers offer these freebies, which is a great way to get to know them and evaluate their teaching methods before buying one of their courses.)

In any case, the more familiar you are with David Joseph Katz’s teaching methods, and the more you enjoy them, the more likely it is that React – Mastering Test Driven Development will be a good fit for you.

(P.S.: We strongly encourage you to seek out some free instruction from David Joseph Katz before purchasing this course, since it’s one of the best ways to determine whether R-MTDD will be helpful for you.)

Are “React – Mastering Test Driven Development” reviews generally positive?

On the bottom of the R-MTDD page, you can read student reviews of the class.

Prior to August 20, 2025, there were 4,079 students enrolled, 1,368 reviews / ratings, and it was overall rated 4.5 out of 5.

Obviously, the more highly other students rate R-MTDD the better, but no matter what, keep an open mind when reading the reviews, since you might still like a course a great deal that other students dislike.

After all, everyone’s got their own opinion.

We recommend that you spend only a couple minutes scanning the R-MTDD reviews to get an overall sense of them. You don’t have to read each one!

Is David Joseph Katz responsive to student questions in the R-MTDD training?

You can see what other students have to say about this in their R-MTDD reviews.

But, our simple all time favorite way of gauging an instructor’s responsiveness is to simply email the instructor and see if or how they respond.

In this case, Udemy has a messaging system for students / anyone who has an account, and you can send David Joseph Katz a message through this system quite easily, even if you haven’t bought R-MTDD yet.

For example, you could say, “Hi, and I came across R-MTDD while looking at Development courses on Udemy. If I enroll in your training, would you mind if I asked you any questions along the way?”

If you use this approach, the response (or lack of response) from the professor will tell you everything.

Obviously, the quicker the response the better!

Are you comfortable going through the lessons in React – Mastering Test Driven Development on your own, online?

This is a big one, because React – Mastering Test Driven Development is an online course as opposed to a course that you physically take in a classroom.

Of course, you will need a good internet connection to have access to the course material and lessons, but beyond that, you also have to be comfortable being self motivated to some degree, being on your own, and not having any physical interaction with any of the other students taking React – Mastering Test Driven Development.

Yes, you will be able to interact with the students and the teacher, David Joseph Katz, online, but it’s a different kind of experience than what you’d get if you were interacting with them in person.

This is not a big deal to most people, but it might be something for you to consider if you feel like you do better taking classes in person rather than learning online.

Do the pros / benefits of R-MTDD make it worth your time?

Ideally, if you’ve gone through the evaluation steps above, you have a list of positive things about the React – Mastering Test Driven Development training that looks something like this:

• The purpose of R-MTDD can be clearly grasped and understood, and its lesson structure is clear, specific, and well organized
• David Joseph Katz is well qualified to teach this subject matter, has good teaching abilities, and is responsive to student questions
• Other R-MTDD students have great things to say about the program

Other benefits include:

• You get to go through R-MTDD at your own pace
• You join a community of 4,079 other students taking the course
• You get lifetime access to the training
• All updates to the training are free
• You have a 30 day money back guarantee

Even if there are some things that you don’t like about the program, so what?

The question is simply this: do you think that R-MTDD would be worth your time, even if there are some things that could be better about it?

Can you comfortably afford R-MTDD?

Can you comfortably afford the cost of React – Mastering Test Driven Development?

This is an important question to answer, because even if you think R-MTDD sounds like the greatest online class in the world, it’s still not worth taking if you can’t comfortably afford it!

Before August 20, 2025, the price was $14.99 before any Udemy discount, and you were able to pay with a credit card.

Keep in mind that this is a Udemy online course, and there’s a great chance that you can get a solid discount on R-MTDD with Udemy coupons / promo codes, especially with the strategies we provide for helping you find the best, most popular coupons available.

We’ll cover that in greater detail in the next section, because at the end of the day, its important that you can learn whatever you want to learn without getting into a lot of credit card debt.

How can you maximize your discount on React – Mastering Test Driven Development?

By far, the easiest way to get the best and biggest discount on this course is to use the React – Mastering Test Driven Development discount code link at the top of this page.

It will instantly give you the best coupon code we could find for David Joseph Katz’s online training.

We don’t believe there’s a bigger discount than the one we provided, but if for some reason you’d like to try find one, you can use the methods below to hunt for the best R-MTDD course coupons and promo codes you can find.

FYI, the methods below will help you not just with getting R-MTDD for a better price, but also with any other David Joseph Katz Udemy course that you’d like to get for cheaper.

How can Google help you get a R-MTDD discount?

To use this method, do a Google search for the R-MTDD training, but in your search query, be sure to add words like coupon code, promo code, deal, sale, discount, and Udemy.

For example, you might do a search for “Udemy React – Mastering Test Driven Development promo code” or “React – Mastering Test Driven Development udemy coupon codes” and see what turns up.

Similarly, you can use the same combination of search terms with David Joseph Katz’s name and see what happens.

For example, you might do a Google search for “David Joseph Katz Udemy coupons” or “David Joseph Katz course coupon codes” and see if that helps you.

However, in general, it’s far more powerful to do a search for deals and coupon codes with the actual training’s name, than with the instructor’s name.

So in this case, for example, prioritize searches for “React – Mastering Test Driven Development coupons” rather than “David Joseph Katz coupons”.

How can a Udemy sale get you R-MTDD for cheaper?

Every once in while, Udemy will do a sitewide sale where they offer all (or almost all) their courses at a discounted price. For example, one of the best sales is where every course is only $10 or $9.99.

So, if you’re interested in saving as much money as possible, you could wait and see if you can get R-MTDD for this cheaper Udemy sale price one day.

The problem is that these sales only occur sporadically, so you might be waiting for a while. Also, if David Joseph Katz decides not to participate in the site wide sale, then you won’t get a discount on R-MTDD, even though you could get a great discount on almost any other class at Udemy!

To understand this, think of there as being two different coupon categories for the R-MTDD course. Category one is an official Udemy coupon (which instructors can opt out of), while category two is a coupon offered directly by the instructor.

At the end of the day, it doesn’t matter what kind of a coupon tag you’re dealing with (for example, “officially from Udemy” or “officially from the instructor”), as long as long as as you’re dealing with active coupons that get you a better price.

How can you get a R-MTDD discount from David Joseph Katz?

If you’re really serious about getting “React – Mastering Test Driven Development” for the cheapest price possible, then perhaps one of the most powerful things you can do is get a coupon code straight from David Joseph Katz, instead of waiting for a Udemy sale.

To do this, you can use either the direct approach or an indirect approach to try to get your discount.

With the direct approach, the big idea is to simply get David Joseph Katz’s contact info in some way or another (whether it’s email, or Twitter, or whatever else).

Then you send a message saying something like “I’m interested in enrolling in React – Mastering Test Driven Development. Do you happen to currently have an active coupon code for it that I could use?” (And then, hopefully, you’ll get a reply with your discount code.)

On the other hand, with the indirect approach, you join David Joseph Katz’s mailing list, if you can find it, and then you hope that at some time R-MTDD will be promoted to you at a discount.

By far, the more powerful approach is the direct approach, because it tends to get results faster. But you can experiment with the indirect approach and see if it works for you.

Can you get R-MTDD for free?

Of course, the best possible price for the R-MTDD training is free! As in, you pay no money whatsoever.

And guess what? Sometimes Udemy instructors provide coupon codes that enable students to take their courses for free. So, perhaps it’s possible that David Joseph Katz has done this.

Basically, if you’re trying to get this program for free, you will want to search for the course’s name along with other words like free coupon, or 100 off coupon.

For example, you might do a google search for “React – Mastering Test Driven Development free coupon” or “React – Mastering Test Driven Development 100 off coupon” and see what happens.

But keep this in mind: often, Udemy teachers will offer a free coupon for their course when it first opens to get some publicity and reviews. And then, after a few days, they’ll make the coupon expired.

So even David Joseph Katz has offered free coupons for R-MTDD in the past, the odds are likely they will all be currently expired. This is a common pattern that we have found.

What about a R-MTDD free download?

It’s important to understand that there’s a difference between getting full access to the R-MTDD training for free legally with a free coupon code vs. finding a way to download R-MTDD illegally.

If you really want to go the download route, you can do a google search for something like “React – Mastering Test Driven Development download”.

And if that doesn’t get you the results you want, you can add the word “free” to your search.

For example, perhaps you could do a google search for “React – Mastering Test Driven Development free download”.

However, even if you get some results from these searches, we do not recommend that you take this course of action.

First of all, there are some shady sites out there that could be trying to infect your computer.

Second, David Joseph Katz created this course and deserves monetary compensation for it.

And third, if you go the free download route, you’ll be missing out on a lot of value, because you won’t be able to ask the instructor questions or interact with the other 4,079 students enrolled in the program.

And now you’re super bummed, because you feel like it wasn’t money well spent.

Well, guess what?

Udemy offers a rock solid 30 day money back guarantee on all their courses, so you can get a refund on R-MTDD no matter what. And this means there is absolutely no risk.

Indeed, even if you left a super negative, critical review on the R-MTDD training, and then asked for your money back, you’d get a refund. For better or worse, there’s nothing David Joseph Katz could do about it, since it is simply Udemy policy.

To sum it up: yes, you can get a full refund, so at the end of the day, don’t worry about the possibility of purchasing R-MTDD and not liking it, since you can always get your money back.

In our review of this course, we try to help you answer all of your most important questions about React JS – Mastering Redux as quickly and efficiently as possible, so that you can determine whether this online education training is worth your time and money.

Feel free to jump to whatever question you want answered the most.

Here’s what you’ll learn:

Why use RJ-MR as an abbreviation of the course name?

During our React JS – Mastering Redux course review, you might sometimes see us refer to it as RJ-MR for the following 2 reasons:

1. We created the acronym by taking the first letter of every word (which was very ingenious and innovative, we know)
2. We’re lazy and RJ-MR is simpler and easier for reviewing purposes

The full course name is 26 characters long, including blanks, while RJ-MR is 5 characters long.

You do the math.

Okay, we’ll do the math. We’re saving 21 characters every time we use RJ-MR.

So, just a heads up that we’ll be using this abbreviation sometimes, so you’re not left scratching your head and wondering what the heck we’re talking about whenever we refer to RJ-MR throughout the remainder of this review.

Is the React JS – Mastering Redux course for you?

To determine whether David Joseph Katz’s Udemy course is a good fit for you or not, ask yourself the following questions down below.

The more you answer “yes” to each question, the more likely it is that you’ll like this course.

Can you understand what David Joseph Katz’s course is about in 30 seconds or less?

Hopefully, you can easily grasp in 10 seconds or less what this online course is about simply by taking a look at the title that David Joseph Katz chose for the course, “React JS – Mastering Redux”, as well as its subtitle: “Build the React JS and Redux apps of your dreams! Learn JavaScript, ES6, APIs, and Full Web App Development in ReactJS!”.

This combo of title and subtitle should be enough to communicate the purpose of the training if David Joseph Katz is a good, clear communicator (which, of course, you want in a teacher).

In our opinion, if you still don’t know what RJ-MR is about after looking at these two things, then this is a red flag, and you might be better off not taking this class.

Among other things, it means David Joseph Katz hasn’t clearly and accurately conveyed what the course is about and might not be the best teacher for you.

For similar reasons, it’s important that you’re able to clearly understand what React JS – Mastering Redux is all about from the first few lines of the course description.

So take just a few seconds to read the opening lines down below and see what you think of them. 

Opening lines of David Joseph Katz’s official description of RJ-MR

You will become an in-demand software engineer by taking this course on React JS and Redux. As one of the most popular pairs of frameworks, learning React and Redux is a must. Simply put, learning React will open doors and jobs for you.

This project-based course will have you coding right away. By building four carefully thought-out example applications, you will sharpen your skills in modern web development.

First, learn the essentials of ReactJS by going through the main concepts. Then build your first React application to get familiar with the essentials. Second, create your first Redux application to learn how to pair this elegant and complex framework with React. Next, build an application that uses an API along with routing for multiple pages. Finally, build an additional app that works with another API and has more advanced redux mechanics.

(Read more about this course on the official course page.)

Does RJ-MR pass the 30 Seconds Test?

You can read a lot more about React JS – Mastering Redux on the official course page on Udemy, but the point is this: are the title, subtitle, and just the first few lines of the description enough to help you understand what the course is about?

If so, David Joseph Katz has done a good job and can be considered more trustworthy and a good communicator, which are important qualities for any teacher.

And, if not, maybe you’re better off looking at other Development classes that are more clearly defined and more tailored to your specific interests.

Did React JS – Mastering Redux appeal to you in 30 seconds or less?

Now that you’ve done the 30 Second Test with RJ-MR above, what is your gut reaction to this Development course with only the basic information of its title, subtitle, and the first few opening lines of its official course summary?

Did David Joseph Katz do a good job conveying its subject matter, and did it immediately get your attention and appeal to you?

If so, David Joseph Katz’s online course is certainly worth considering some more.

But if not, perhaps it’s in your best interest to consider some other Development courses instead, because clear communication and being able to hook and maintain your interest are two very important qualities for your online learning success.

Does David Joseph Katz sound like a course instructor you’d like to learn from?

You’ve already learned how to use The 30 Second Test to make a quick evaluation of whether the RJ-MR course is worth taking.

We have a similar 15 Second Bio Test where you read only the first few lines of an instructor’s background — in this case, David Joseph Katz’s background — and then you make a quick, snap judgment as to whether you think the instructor would be ideal for you.

There is no right or wrong answer. It’s just about going with your gut instinct. What might appeal to one potential student might alienate another, and vice versa.

(FYI, all Udemy instructors, including David Joseph Katz, have a Udemy profile on their course page, so you can easily check for a bio and background on the Udemy website that way. We’re only including the first few lines of the bio down below for The 15 Second Bio Test).

Opening lines from David Joseph Katz’s Udemy bio

David is a software engineer at Zendesk, with a Bachelor of Computer Science from the University of San Francisco.

(Learn more about this instructor on the official course page.)

What did you think about David Joseph Katz after reading just the first few lines of the bio above?

After reading just the first few lines about David Joseph Katz, did it make you more or less interested in taking the RJ-MR course?

And did it make you feel like David Joseph Katz was more or less credible and qualified to teach React JS – Mastering Redux?

Finally, overall, did you feel like you’d receive the proper training from the instructor of this Development course?

As always, we encourage you to listen to your gut instinct, which is different for every student.

Are the RJ-MR lessons clear, specific, and organized well?

Part of the (good) problem with Udemy’s online courses, such as the React JS – Mastering Redux course, is that the instructors are constantly updating them, including adding and renaming lessons.

So it makes no sense whatsoever for us to list out all the modules and lessons in the RJ-MR course here, because you can just as easily go to the Udemy course page and get all the up to date course structure as of right now.

We do, however, have some tips about reviewing David Joseph Katz’s course structure, so that you can get a better sense of whether this program is worth your time or not.

In a nutshell, you want to scan the the titles of the different sections and lessons of the course, and verify that they are clearly relevant to the course’s name, React JS – Mastering Redux, as well as the course’s subtitle, Build the React JS and Redux apps of your dreams! Learn JavaScript, ES6, APIs, and Full Web App Development in ReactJS!.

If the section names and lessons are clear, specific, and relevant, then it’s a good sign that RJ-MR is potentially a good, useful course for you, and you can have more confidence in David Joseph Katz’s teaching abilities and lesson planning.

On the other hand, if the module names are confusing, vague, or irrelevant, then this is a red flag, which might indicate that the program is worth skipping.

Have you taken some free lessons from David Joseph Katz that you enjoyed?

Have you already learned something from David Joseph Katz that you valued or enjoyed?

For example, does the React JS – Mastering Redux training have some free lessons that you can try? (Almost all Udemy instructors will give you at least one or two lessons for free to help you make a better, more informed decision before enrolling in their course.)

But if you weren’t able to get any RJ-MR lessons for free, have you perhaps watched a YouTube video by David Joseph Katz, or perhaps come across this instructor’s thoughts on Quora, Facebook, LinkedIn, Github, Reddit, or some other platform?

Or have you perhaps even taken one of David Joseph Katz’s free courses or free webinars? (Many online teachers offer these freebies, which is a great way to get to know them and evaluate their teaching methods before buying one of their courses.)

In any case, the more familiar you are with David Joseph Katz’s teaching methods, and the more you enjoy them, the more likely it is that React JS – Mastering Redux will be a good fit for you.

(P.S.: We strongly encourage you to seek out some free instruction from David Joseph Katz before purchasing this course, since it’s one of the best ways to determine whether RJ-MR will be helpful for you.)

Are “React JS – Mastering Redux” reviews generally positive?

On the bottom of the RJ-MR page, you can read student reviews of the class.

Prior to August 20, 2025, there were 2,453 students enrolled, 991 reviews / ratings, and it was overall rated 4.3 out of 5.

Obviously, the more highly other students rate RJ-MR the better, but no matter what, keep an open mind when reading the reviews, since you might still like a course a great deal that other students dislike.

After all, everyone’s got their own opinion.

We recommend that you spend only a couple minutes scanning the RJ-MR reviews to get an overall sense of them. You don’t have to read each one!

Is David Joseph Katz responsive to student questions in the RJ-MR training?

You can see what other students have to say about this in their RJ-MR reviews.

But, our simple all time favorite way of gauging an instructor’s responsiveness is to simply email the instructor and see if or how they respond.

In this case, Udemy has a messaging system for students / anyone who has an account, and you can send David Joseph Katz a message through this system quite easily, even if you haven’t bought RJ-MR yet.

For example, you could say, “Hi, and I came across RJ-MR while looking at Development courses on Udemy. If I enroll in your training, would you mind if I asked you any questions along the way?”

If you use this approach, the response (or lack of response) from the professor will tell you everything.

Obviously, the quicker the response the better!

Are you comfortable going through the lessons in React JS – Mastering Redux on your own, online?

This is a big one, because React JS – Mastering Redux is an online course as opposed to a course that you physically take in a classroom.

Of course, you will need a good internet connection to have access to the course material and lessons, but beyond that, you also have to be comfortable being self motivated to some degree, being on your own, and not having any physical interaction with any of the other students taking React JS – Mastering Redux.

Yes, you will be able to interact with the students and the teacher, David Joseph Katz, online, but it’s a different kind of experience than what you’d get if you were interacting with them in person.

This is not a big deal to most people, but it might be something for you to consider if you feel like you do better taking classes in person rather than learning online.

Do the pros / benefits of RJ-MR make it worth your time?

Ideally, if you’ve gone through the evaluation steps above, you have a list of positive things about the React JS – Mastering Redux training that looks something like this:

• The purpose of RJ-MR can be clearly grasped and understood, and its lesson structure is clear, specific, and well organized
• David Joseph Katz is well qualified to teach this subject matter, has good teaching abilities, and is responsive to student questions
• Other RJ-MR students have great things to say about the program

Other benefits include:

• You get to go through RJ-MR at your own pace
• You join a community of 2,453 other students taking the course
• You get lifetime access to the training
• All updates to the training are free
• You have a 30 day money back guarantee

Even if there are some things that you don’t like about the program, so what?

The question is simply this: do you think that RJ-MR would be worth your time, even if there are some things that could be better about it?

Can you comfortably afford RJ-MR?

Can you comfortably afford the cost of React JS – Mastering Redux?

This is an important question to answer, because even if you think RJ-MR sounds like the greatest online class in the world, it’s still not worth taking if you can’t comfortably afford it!

Before August 20, 2025, the price was $12.99 before any Udemy discount, and you were able to pay with a credit card.

Keep in mind that this is a Udemy online course, and there’s a great chance that you can get a solid discount on RJ-MR with Udemy coupons / promo codes, especially with the strategies we provide for helping you find the best, most popular coupons available.

We’ll cover that in greater detail in the next section, because at the end of the day, its important that you can learn whatever you want to learn without getting into a lot of credit card debt.

How can you maximize your discount on React JS – Mastering Redux?

By far, the easiest way to get the best and biggest discount on this course is to use the React JS – Mastering Redux discount code link at the top of this page.

It will instantly give you the best coupon code we could find for David Joseph Katz’s online training.

We don’t believe there’s a bigger discount than the one we provided, but if for some reason you’d like to try find one, you can use the methods below to hunt for the best RJ-MR course coupons and promo codes you can find.

FYI, the methods below will help you not just with getting RJ-MR for a better price, but also with any other David Joseph Katz Udemy course that you’d like to get for cheaper.

How can Google help you get a RJ-MR discount?

To use this method, do a Google search for the RJ-MR training, but in your search query, be sure to add words like coupon code, promo code, deal, sale, discount, and Udemy.

For example, you might do a search for “Udemy React JS – Mastering Redux promo code” or “React JS – Mastering Redux udemy coupon codes” and see what turns up.

Similarly, you can use the same combination of search terms with David Joseph Katz’s name and see what happens.

For example, you might do a Google search for “David Joseph Katz Udemy coupons” or “David Joseph Katz course coupon codes” and see if that helps you.

However, in general, it’s far more powerful to do a search for deals and coupon codes with the actual training’s name, than with the instructor’s name.

So in this case, for example, prioritize searches for “React JS – Mastering Redux coupons” rather than “David Joseph Katz coupons”.

How can a Udemy sale get you RJ-MR for cheaper?

Every once in while, Udemy will do a sitewide sale where they offer all (or almost all) their courses at a discounted price. For example, one of the best sales is where every course is only $10 or $9.99.

So, if you’re interested in saving as much money as possible, you could wait and see if you can get RJ-MR for this cheaper Udemy sale price one day.

The problem is that these sales only occur sporadically, so you might be waiting for a while. Also, if David Joseph Katz decides not to participate in the site wide sale, then you won’t get a discount on RJ-MR, even though you could get a great discount on almost any other class at Udemy!

To understand this, think of there as being two different coupon categories for the RJ-MR course. Category one is an official Udemy coupon (which instructors can opt out of), while category two is a coupon offered directly by the instructor.

At the end of the day, it doesn’t matter what kind of a coupon tag you’re dealing with (for example, “officially from Udemy” or “officially from the instructor”), as long as long as as you’re dealing with active coupons that get you a better price.

How can you get a RJ-MR discount from David Joseph Katz?

If you’re really serious about getting “React JS – Mastering Redux” for the cheapest price possible, then perhaps one of the most powerful things you can do is get a coupon code straight from David Joseph Katz, instead of waiting for a Udemy sale.

To do this, you can use either the direct approach or an indirect approach to try to get your discount.

With the direct approach, the big idea is to simply get David Joseph Katz’s contact info in some way or another (whether it’s email, or Twitter, or whatever else).

Then you send a message saying something like “I’m interested in enrolling in React JS – Mastering Redux. Do you happen to currently have an active coupon code for it that I could use?” (And then, hopefully, you’ll get a reply with your discount code.)

On the other hand, with the indirect approach, you join David Joseph Katz’s mailing list, if you can find it, and then you hope that at some time RJ-MR will be promoted to you at a discount.

By far, the more powerful approach is the direct approach, because it tends to get results faster. But you can experiment with the indirect approach and see if it works for you.

Can you get RJ-MR for free?

Of course, the best possible price for the RJ-MR training is free! As in, you pay no money whatsoever.

And guess what? Sometimes Udemy instructors provide coupon codes that enable students to take their courses for free. So, perhaps it’s possible that David Joseph Katz has done this.

Basically, if you’re trying to get this program for free, you will want to search for the course’s name along with other words like free coupon, or 100 off coupon.

For example, you might do a google search for “React JS – Mastering Redux free coupon” or “React JS – Mastering Redux 100 off coupon” and see what happens.

But keep this in mind: often, Udemy teachers will offer a free coupon for their course when it first opens to get some publicity and reviews. And then, after a few days, they’ll make the coupon expired.

So even David Joseph Katz has offered free coupons for RJ-MR in the past, the odds are likely they will all be currently expired. This is a common pattern that we have found.

What about a RJ-MR free download?

It’s important to understand that there’s a difference between getting full access to the RJ-MR training for free legally with a free coupon code vs. finding a way to download RJ-MR illegally.

If you really want to go the download route, you can do a google search for something like “React JS – Mastering Redux download”.

And if that doesn’t get you the results you want, you can add the word “free” to your search.

For example, perhaps you could do a google search for “React JS – Mastering Redux free download”.

However, even if you get some results from these searches, we do not recommend that you take this course of action.

First of all, there are some shady sites out there that could be trying to infect your computer.

Second, David Joseph Katz created this course and deserves monetary compensation for it.

And third, if you go the free download route, you’ll be missing out on a lot of value, because you won’t be able to ask the instructor questions or interact with the other 2,453 students enrolled in the program.

Can you get a refund on React JS – Mastering Redux if you don’t like it?

Let’s say that you used our tips above, and you were able to buy the RJ-MR training at a fantastic discounted price. So at this point, you’re super excited.

Then, you actually dive into David Joseph Katz’s course, and you discover that it just isn’t for you for whatever reason.

And now you’re super bummed, because you feel like it wasn’t money well spent.

Well, guess what?

Udemy offers a rock solid 30 day money back guarantee on all their courses, so you can get a refund on RJ-MR no matter what. And this means there is absolutely no risk.

Indeed, even if you left a super negative, critical review on the RJ-MR training, and then asked for your money back, you’d get a refund. For better or worse, there’s nothing David Joseph Katz could do about it, since it is simply Udemy policy.

To sum it up: yes, you can get a full refund, so at the end of the day, don’t worry about the possibility of purchasing RJ-MR and not liking it, since you can always get your money back.

What is OCP’s overall rating of React JS – Mastering Redux?

During this RJ-MR review, you’ve learned about some of the unusual ways we like to evaluate courses, such as with The 30 Second Test and The 15 Second Bio Test.

So our overall review process is perhaps a little unusual and different from other reviews out there. Keep this in mind when you consider the overall rating / score that we have given this course.

Anyway, after taking a look at the RJ-MR training, the instructor, David Joseph Katz, and reading what other students have said about this program, we give it an overall rating of 4.4 out of 5.

Ultimately, though, what matters most is what you would rate it based on the same criteria.

Feel free to jump to whatever question you want answered the most.

Here’s what you’ll learn:

Why use NS&P-MBWD as an abbreviation of the course name?

During our Node, SQL, & PostgreSQL – Mastering Backend Web Development course review, you might sometimes see us refer to it as NS&P-MBWD for the following 2 reasons:

1. We created the acronym by taking the first letter of every word (which was very ingenious and innovative, we know)
2. We’re lazy and NS&P-MBWD is simpler and easier for reviewing purposes

The full course name is 59 characters long, including blanks, while NS&P-MBWD is 9 characters long.

You do the math.

Okay, we’ll do the math. We’re saving 50 characters every time we use NS&P-MBWD.

So, just a heads up that we’ll be using this abbreviation sometimes, so you’re not left scratching your head and wondering what the heck we’re talking about whenever we refer to NS&P-MBWD throughout the remainder of this review.

NodeJS, Databases, Express, JS, ES6, + more!”.

This combo of title and subtitle should be enough to communicate the purpose of the training if David Joseph Katz is a good, clear communicator (which, of course, you want in a teacher).

(P.S.: We strongly encourage you to seek out some free instruction from David Joseph Katz before purchasing this course, since it’s one of the best ways to determine whether NS&P-MBWD will be helpful for you.)

Are “Node, SQL, & PostgreSQL – Mastering Backend Web Development” reviews generally positive?

On the bottom of the NS&P-MBWD page, you can read student reviews of the class.

Prior to August 20, 2025, there were 1,761 students enrolled, 717 reviews / ratings, and it was overall rated 4.1 out of 5.

Obviously, the more highly other students rate NS&P-MBWD the better, but no matter what, keep an open mind when reading the reviews, since you might still like a course a great deal that other students dislike.

After all, everyone’s got their own opinion.

We recommend that you spend only a couple minutes scanning the NS&P-MBWD reviews to get an overall sense of them. You don’t have to read each one!

Is David Joseph Katz responsive to student questions in the NS&P-MBWD training?

You can see what other students have to say about this in their NS&P-MBWD reviews.

But, our simple all time favorite way of gauging an instructor’s responsiveness is to simply email the instructor and see if or how they respond.

In this case, Udemy has a messaging system for students / anyone who has an account, and you can send David Joseph Katz a message through this system quite easily, even if you haven’t bought NS&P-MBWD yet.

For example, you could say, “Hi, and I came across NS&P-MBWD while looking at Development courses on Udemy. If I enroll in your training, would you mind if I asked you any questions along the way?”

If you use this approach, the response (or lack of response) from the professor will tell you everything.

Obviously, the quicker the response the better!

Are you comfortable going through the lessons in Node, SQL, & PostgreSQL – Mastering Backend Web Development on your own, online?

This is a big one, because Node, SQL, & PostgreSQL – Mastering Backend Web Development is an online course as opposed to a course that you physically take in a classroom.

Of course, you will need a good internet connection to have access to the course material and lessons, but beyond that, you also have to be comfortable being self motivated to some degree, being on your own, and not having any physical interaction with any of the other students taking Node, SQL, & PostgreSQL – Mastering Backend Web Development.

Yes, you will be able to interact with the students and the teacher, David Joseph Katz, online, but it’s a different kind of experience than what you’d get if you were interacting with them in person.

This is not a big deal to most people, but it might be something for you to consider if you feel like you do better taking classes in person rather than learning online.

Can you comfortably afford NS&P-MBWD?

Can you comfortably afford the cost of Node, SQL, & PostgreSQL – Mastering Backend Web Development?

This is an important question to answer, because even if you think NS&P-MBWD sounds like the greatest online class in the world, it’s still not worth taking if you can’t comfortably afford it!

Before August 20, 2025, the price was $12.99 before any Udemy discount, and you were able to pay with a credit card.

Keep in mind that this is a Udemy online course, and there’s a great chance that you can get a solid discount on NS&P-MBWD with Udemy coupons / promo codes, especially with the strategies we provide for helping you find the best, most popular coupons available.

We’ll cover that in greater detail in the next section, because at the end of the day, its important that you can learn whatever you want to learn without getting into a lot of credit card debt.

How can you maximize your discount on Node, SQL, & PostgreSQL – Mastering Backend Web Development?

By far, the easiest way to get the best and biggest discount on this course is to use the Node, SQL, & PostgreSQL – Mastering Backend Web Development discount code link at the top of this page.

It will instantly give you the best coupon code we could find for David Joseph Katz’s online training.

We don’t believe there’s a bigger discount than the one we provided, but if for some reason you’d like to try find one, you can use the methods below to hunt for the best NS&P-MBWD course coupons and promo codes you can find.

FYI, the methods below will help you not just with getting NS&P-MBWD for a better price, but also with any other David Joseph Katz Udemy course that you’d like to get for cheaper.

How can Google help you get a NS&P-MBWD discount?

To use this method, do a Google search for the NS&P-MBWD training, but in your search query, be sure to add words like coupon code, promo code, deal, sale, discount, and Udemy.

For example, you might do a search for “Udemy Node, SQL, & PostgreSQL – Mastering Backend Web Development promo code” or “Node, SQL, & PostgreSQL – Mastering Backend Web Development udemy coupon codes” and see what turns up.

Similarly, you can use the same combination of search terms with David Joseph Katz’s name and see what happens.

For example, you might do a Google search for “David Joseph Katz Udemy coupons” or “David Joseph Katz course coupon codes” and see if that helps you.

However, in general, it’s far more powerful to do a search for deals and coupon codes with the actual training’s name, than with the instructor’s name.

So in this case, for example, prioritize searches for “Node, SQL, & PostgreSQL – Mastering Backend Web Development coupons” rather than “David Joseph Katz coupons”.

How can a Udemy sale get you NS&P-MBWD for cheaper?

Every once in while, Udemy will do a sitewide sale where they offer all (or almost all) their courses at a discounted price. For example, one of the best sales is where every course is only $10 or $9.99.

So, if you’re interested in saving as much money as possible, you could wait and see if you can get NS&P-MBWD for this cheaper Udemy sale price one day.

The problem is that these sales only occur sporadically, so you might be waiting for a while. Also, if David Joseph Katz decides not to participate in the site wide sale, then you won’t get a discount on NS&P-MBWD, even though you could get a great discount on almost any other class at Udemy!

To understand this, think of there as being two different coupon categories for the NS&P-MBWD course. Category one is an official Udemy coupon (which instructors can opt out of), while category two is a coupon offered directly by the instructor.

At the end of the day, it doesn’t matter what kind of a coupon tag you’re dealing with (for example, “officially from Udemy” or “officially from the instructor”), as long as long as as you’re dealing with active coupons that get you a better price.

How can you get a NS&P-MBWD discount from David Joseph Katz?

If you’re really serious about getting “Node, SQL, & PostgreSQL – Mastering Backend Web Development” for the cheapest price possible, then perhaps one of the most powerful things you can do is get a coupon code straight from David Joseph Katz, instead of waiting for a Udemy sale.

To do this, you can use either the direct approach or an indirect approach to try to get your discount.

With the direct approach, the big idea is to simply get David Joseph Katz’s contact info in some way or another (whether it’s email, or Twitter, or whatever else).

Then you send a message saying something like “I’m interested in enrolling in Node, SQL, & PostgreSQL – Mastering Backend Web Development. Do you happen to currently have an active coupon code for it that I could use?” (And then, hopefully, you’ll get a reply with your discount code.)

On the other hand, with the indirect approach, you join David Joseph Katz’s mailing list, if you can find it, and then you hope that at some time NS&P-MBWD will be promoted to you at a discount.

By far, the more powerful approach is the direct approach, because it tends to get results faster. But you can experiment with the indirect approach and see if it works for you.

Can you get NS&P-MBWD for free?

Of course, the best possible price for the NS&P-MBWD training is free! As in, you pay no money whatsoever.

And guess what? Sometimes Udemy instructors provide coupon codes that enable students to take their courses for free. So, perhaps it’s possible that David Joseph Katz has done this.

Basically, if you’re trying to get this program for free, you will want to search for the course’s name along with other words like free coupon, or 100 off coupon.

For example, you might do a google search for “Node, SQL, & PostgreSQL – Mastering Backend Web Development free coupon” or “Node, SQL, & PostgreSQL – Mastering Backend Web Development 100 off coupon” and see what happens.

But keep this in mind: often, Udemy teachers will offer a free coupon for their course when it first opens to get some publicity and reviews. And then, after a few days, they’ll make the coupon expired.

So even David Joseph Katz has offered free coupons for NS&P-MBWD in the past, the odds are likely they will all be currently expired. This is a common pattern that we have found.

What about a NS&P-MBWD free download?

It’s important to understand that there’s a difference between getting full access to the NS&P-MBWD training for free legally with a free coupon code vs. finding a way to download NS&P-MBWD illegally.

If you really want to go the download route, you can do a google search for something like “Node, SQL, & PostgreSQL – Mastering Backend Web Development download”.

And if that doesn’t get you the results you want, you can add the word “free” to your search.

For example, perhaps you could do a google search for “Node, SQL, & PostgreSQL – Mastering Backend Web Development free download”.

However, even if you get some results from these searches, we do not recommend that you take this course of action.

First of all, there are some shady sites out there that could be trying to infect your computer.

Second, David Joseph Katz created this course and deserves monetary compensation for it.

And third, if you go the free download route, you’ll be missing out on a lot of value, because you won’t be able to ask the instructor questions or interact with the other 1,761 students enrolled in the program.

Can you get a refund on Node, SQL, & PostgreSQL – Mastering Backend Web Development if you don’t like it?

Let’s say that you used our tips above, and you were able to buy the NS&P-MBWD training at a fantastic discounted price. So at this point, you’re super excited.

Then, you actually dive into David Joseph Katz’s course, and you discover that it just isn’t for you for whatever reason.

And now you’re super bummed, because you feel like it wasn’t money well spent.

Well, guess what?

Udemy offers a rock solid 30 day money back guarantee on all their courses, so you can get a refund on NS&P-MBWD no matter what. And this means there is absolutely no risk.

Indeed, even if you left a super negative, critical review on the NS&P-MBWD training, and then asked for your money back, you’d get a refund. For better or worse, there’s nothing David Joseph Katz could do about it, since it is simply Udemy policy.

To sum it up: yes, you can get a full refund, so at the end of the day, don’t worry about the possibility of purchasing NS&P-MBWD and not liking it, since you can always get your money back.
