Learning Data Structures in JavaScript from Scratch review for 2024

In our review of this course, we try to help you answer all of your most important questions about Learning Data Structures in JavaScript from Scratch 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 LDSIJFS as an abbreviation of the course name?

During our Learning Data Structures in JavaScript from Scratch course review, you might sometimes see us refer to it as LDSIJFS 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 LDSIJFS is simpler and easier for reviewing purposes

The full course name is 51 characters long, including blanks, while LDSIJFS is 7 characters long.

You do the math.

Okay, we’ll do the math. We’re saving 44 characters every time we use LDSIJFS.

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 LDSIJFS throughout the remainder of this review.

Is the Learning Data Structures in JavaScript from Scratch course for you?

To determine whether Eric Traub’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 Eric Traub’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 Eric Traub chose for the course, “Learning Data Structures in JavaScript from Scratch”, as well as its subtitle: “Write more efficient & performant code by learning data structures. Be well prepared for technical interview questions.”.

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

In our opinion, if you still don’t know what LDSIJFS 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 Eric Traub 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 Learning Data Structures in JavaScript from Scratch 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 Eric Traub’s official description of LDSIJFS

This course teaches data structures (linked lists, binary search trees, hash tables) from the ground up. Data structures allow you to improve the efficiency, performance, speed, and scalability of your code/programs/applications. You will learn what data structures are, why they are important, and how to code them out in JavaScript. You will also learn other important programming concepts along the way such as recursion, time complexity, the “this” keyword, the prototype object, and constructor functions, since data structures use these concepts by their very nature. This course heavily uses diagrams and animations to help make understanding the material easier.

This course is also very good for anyone who is interviewing for developer/engineering jobs at both large and small companies. Interviewers will very often ask candidates to write data structures out in code, and this course will prepare you very well to do that. If you have recently graduated from a coding bootcamp or are currently looking for a job, you will find this course to be beneficial. Knowing data structures will help you to excel in technical interviews.

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

Does LDSIJFS pass the 30 Seconds Test?

You can read a lot more about Learning Data Structures in JavaScript from Scratch 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, Eric Traub 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 Learning Data Structures in JavaScript from Scratch appeal to you in 30 seconds or less?

Now that you’ve done the 30 Second Test with LDSIJFS 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 Eric Traub do a good job conveying its subject matter, and did it immediately get your attention and appeal to you?

If so, Eric Traub’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 Eric Traub 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 LDSIJFS 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, Eric Traub’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 Eric Traub, 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 Eric Traub’s Udemy bio

HI! I’m Eric. I currently work as a software engineer in New York City and I have extensive experience working as a teacher, instructing people in a variety of different subjects. I changed my career from teaching to software engineering because of the excitement it brings me and the passion that I have for it. I am lucky enough now to have the opportunity to combine both of these passions – software engineering and teaching!

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

What did you think about Eric Traub after reading just the first few lines of the bio above?

After reading just the first few lines about Eric Traub, did it make you more or less interested in taking the LDSIJFS course?

And did it make you feel like Eric Traub was more or less credible and qualified to teach Learning Data Structures in JavaScript from Scratch?

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 LDSIJFS lessons clear, specific, and organized well?

Part of the (good) problem with Udemy’s online courses, such as the Learning Data Structures in JavaScript from Scratch 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 LDSIJFS 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 Eric Traub’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, Learning Data Structures in JavaScript from Scratch, as well as the course’s subtitle, Write more efficient & performant code by learning data structures. Be well prepared for technical interview questions..

If the section names and lessons are clear, specific, and relevant, then it’s a good sign that LDSIJFS is potentially a good, useful course for you, and you can have more confidence in Eric Traub’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 Eric Traub that you enjoyed?

Have you already learned something from Eric Traub that you valued or enjoyed?

For example, does the Learning Data Structures in JavaScript from Scratch 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 LDSIJFS lessons for free, have you perhaps watched a YouTube video by Eric Traub, 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 Eric Traub’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 Eric Traub’s teaching methods, and the more you enjoy them, the more likely it is that Learning Data Structures in JavaScript from Scratch will be a good fit for you.

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

Are “Learning Data Structures in JavaScript from Scratch” reviews generally positive?

On the bottom of the LDSIJFS page, you can read student reviews of the class.

Prior to April 20, 2024, there were 4,961 students enrolled, 1,861 reviews / ratings, and it was overall rated 4.5 out of 5.

Obviously, the more highly other students rate LDSIJFS 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 LDSIJFS reviews to get an overall sense of them. You don’t have to read each one!

Is Eric Traub responsive to student questions in the LDSIJFS training?

You can see what other students have to say about this in their LDSIJFS 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 Eric Traub a message through this system quite easily, even if you haven’t bought LDSIJFS yet.

For example, you could say, “Hi, and I came across LDSIJFS 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 Learning Data Structures in JavaScript from Scratch on your own, online?

This is a big one, because Learning Data Structures in JavaScript from Scratch 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 Learning Data Structures in JavaScript from Scratch.

Yes, you will be able to interact with the students and the teacher, Eric Traub, 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 LDSIJFS make it worth your time?

Ideally, if you’ve gone through the evaluation steps above, you have a list of positive things about the Learning Data Structures in JavaScript from Scratch training that looks something like this:

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

Other benefits include:

  • You get to go through LDSIJFS at your own pace
  • You join a community of 4,961 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 LDSIJFS would be worth your time, even if there are some things that could be better about it?

Can you comfortably afford LDSIJFS?

Can you comfortably afford the cost of Learning Data Structures in JavaScript from Scratch?

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

Before April 20, 2024, 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 LDSIJFS 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 Learning Data Structures in JavaScript from Scratch?

By far, the easiest way to get the best and biggest discount on this course is to use the Learning Data Structures in JavaScript from Scratch discount code link at the top of this page.

It will instantly give you the best coupon code we could find for Eric Traub’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 LDSIJFS course coupons and promo codes you can find.

FYI, the methods below will help you not just with getting LDSIJFS for a better price, but also with any other Eric Traub Udemy course that you’d like to get for cheaper.

How can Google help you get a LDSIJFS discount?

To use this method, do a Google search for the LDSIJFS 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 Learning Data Structures in JavaScript from Scratch promo code” or “Learning Data Structures in JavaScript from Scratch udemy coupon codes” and see what turns up.

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

For example, you might do a Google search for “Eric Traub Udemy coupons” or “Eric Traub 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 “Learning Data Structures in JavaScript from Scratch coupons” rather than “Eric Traub coupons”.

How can a Udemy sale get you LDSIJFS 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 LDSIJFS 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 Eric Traub decides not to participate in the site wide sale, then you won’t get a discount on LDSIJFS, 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 LDSIJFS 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 LDSIJFS discount from Eric Traub?

If you’re really serious about getting “Learning Data Structures in JavaScript from Scratch” for the cheapest price possible, then perhaps one of the most powerful things you can do is get a coupon code straight from Eric Traub, 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 Eric Traub’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 Learning Data Structures in JavaScript from Scratch. 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 Eric Traub’s mailing list, if you can find it, and then you hope that at some time LDSIJFS 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 LDSIJFS for free?

Of course, the best possible price for the LDSIJFS 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 Eric Traub 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 “Learning Data Structures in JavaScript from Scratch free coupon” or “Learning Data Structures in JavaScript from Scratch 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 Eric Traub has offered free coupons for LDSIJFS 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 LDSIJFS free download?

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

If you really want to go the download route, you can do a google search for something like “Learning Data Structures in JavaScript from Scratch 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 “Learning Data Structures in JavaScript from Scratch 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, Eric Traub 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 4,961 students enrolled in the program.

Can you get a refund on Learning Data Structures in JavaScript from Scratch if you don’t like it?

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

Then, you actually dive into Eric Traub’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 LDSIJFS no matter what. And this means there is absolutely no risk.

Indeed, even if you left a super negative, critical review on the LDSIJFS training, and then asked for your money back, you’d get a refund. For better or worse, there’s nothing Eric Traub 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 LDSIJFS and not liking it, since you can always get your money back.

What is OCP’s overall rating of Learning Data Structures in JavaScript from Scratch?

During this LDSIJFS 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 LDSIJFS training, the instructor, Eric Traub, and reading what other students have said about this program, we give it an overall rating of 4.7 out of 5.

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