Advanced Javascript (Updated 2026) (Udemy.com)

Amazing course, the in-depth explanations are just awesome. This is the best course for advanced JavaScript ever. It teaches the real JavaScript paradigms and things to take care of. This has helped me a lot professionally. I am a big fan of Asim after this course. I have completed his angular course as well which is really well taught. Every point is thoroughly covered and explained by the instructor.

This course explains about the deeper details of JavaScript. Its INCREDIBLE. Certain things that i had been using in JS, i never really grasped the concepts as to why they worked the way they did. All I knew was "this is how you do it, so keep doing it this way." After taking this course I now have a better understanding of not only JS but other 'flavors' of JS like React, Vue, and node. THIS COURSE IS DEFINITELY THE COURSE TO ADVANCE MY CAREER AS A DEVELOPER. I wish I could give it more stars.

Hi! I've just started today but I must say that I really like your course already! I really enjoy learning JavaScript by looking at the process of how the language has evolved over the years. It helps me understand all the newer features and that's exactly what your course does. Also, I love the idea that there is your miniature in the videos. It really draws my attention and I find myself being much more focused on what you are saying, hope it's going to be like this till the end of the course :)

Great course. A lot of useful information. Of course, you won't become a Senior Developer after this course, but, definitely, you will improve/refresh your JS skills before a job interview. Personally, I've found a lot of answers to my questions about JS and filled gaps in my JS skills. I think there might be about 10 other vital questions about JS related to ES6/ES7 and I hope that the course will be updated in the future.

Don't take this course until it has a comprehensive ES6 coverage, at the very least in the topics discussed. This course must be 5 years old in the knowledge it conveys now. In depth and clear explanations, otherwise. To Asim: You can and should do better - you are good in what you do explain

This class is an excellent resource on JavaScript. Explains the complicated parts of JS clearly and concisely. Really liked the sections on Object-Oriented Programming, especially the explanation of Prototypal, Classical, and Pseudo-Classical inheritance. Also, really like the format. Key concepts are asked as a question that you would get in an interview, so the subject matter is relevant in: 1) understanding the fundamental concepts 2) responding to the question with an answer that goes "above and beyond" the standard solution. Definitely recommend this course.

This course talks about many different subjects that many unexperienced developers don't know about, it goes into detail about many different subjects, for example the use of strict, what exactly it does and when to use it, type cohesion, it goes really deep into scopes, scope chains, common errors of the use of scope, uses of IIFE, as well as its advantages, closures, when to use a closure, how they actually work, common errors of closures, when to use them, practical uses, it goes deep into closures, the use of "this", deep understanding of "this", how to use call, apply and bind functions to pass "this" to other functions, it also goes deep into prototypes, the prototype chain, different types of inheritance, the new keyword, classes, Object.create, and Events, this is a very complete course, the only reason I'm giving it a 4, its because its missing in my perspective something really important, which is promises, it doesn't talk about promises at all, and that is a very important topic for experienced developers. with that topic this course will deserve a 5 star rating. the voice of the presenter is not boring at all, I used to get drowsy listening to other presenters but not here. the way he explains, when he is explaining something important he start talking slowly, which is excellent for non english speakers like me, I don't have to rewind the video that many times its clear what he is saying that along with the many many many examples he demonstrates is excellent. I really want to give it a 5 star rating. so please add that topic and I'll rate again.

The course is very straight-forward! It covers many things that i could do not understand by reading a JS book. Examples are helping a lot. But the examples are kinda poor. For instance, in the call, apply and bind lecture, I believe that its important to communicate the that bind does not the function like apply and call but it creates a copy of the function. And that you can pass parameters to bind. (Function currying). Also, I would like to hear more beginner stuff about the CORS and JSONP lectures. Because, it was the first time I countered them. And I did not fully understand them.

Okay after watching this course twice, once a few months ago and once now, I've decided to update my review. These days I'm looking for a job as frontend AngularJS developer and since AngularJS is a JavaScript framework I decided to watch it again before an interview to refresh my memory on some topics and again I got to say this course is so useful and so recommended by me atleast. To sum everything up whether you are a beginner or an advanced developer who wants to start or refresh your memory before an interview this course is what you're looking for. Thanks Asim looking for more courses from you : )

The good examples to understand the important foundations and some tricky parts of JavaScript. Everything is explained really clearly and with all necessary details and multiple examples. The author's voice and the explanation speed are comfortable to understand everything. I do recommend this course and my only wish to the author is to develop it further so the course would describe even more tricky parts of JavaScript.

Like the author and the way he's presenting those complicated ideas but no ES2015+ features makes this outdated and should either be updated or retired.

I feel i know a bit more of JavaScript but my journey doesn't end here its just the beginning.
