Advanced JavaScript Concepts: Gain Modern JS Developer Skills

Clear explanations, got a lot of knowledge about javascript internals, nice course to fill in your gaps

JavaScripts advanced concepts are well explained, in a simple manner.
My favourite topics are related to async function and this course helped me to understand how it works and why are so important.
Thanks Andrei.

Well, finally I’m here!
I didn´t want to give the review without finishing the course previously. So I decided to finish the course first.
I feel excited for having completed the course, sometimes I felt overwhelmed because, you see, this is my first course on Javascript, I’m not even a junior developer, I’m 40 years old, and I’ve worked at the Oil and Gas Industry as an Instrumentation Engineer for 16 years, and a friend of mine recommended me to try coding, so I started taking some free tutorials on YouTube and I took some classes of HTML, CSS and SASS, and considering JavaScript is very popular, I decided to take this course (my first course on JS) in order to have clear concepts, in order to start properly, but I can´t deny that sometimes I feel afraid that I won´t achieve it.
Having this said, regarding this course, and the way that Andrei makes his clases, I just can say it´s awesome, I mean, Andrei is an excellent instructor! I really loved this course, in spite of those clases or exercises that were so hard, for example, when we started the two pillars, with closures I felt sad or a little frustrated, not because of the class, but when I see the complexity of this challenge, or hash tables, I have to confess, I don´t know how to do all the challenges, and that´s why I get frustrated, but this is part of the journey I guess.
If someone reads all of my review, I just can say, I truly recommend this course, just take your time, take notes, do the code, and if you can´t do all of them, don´t stop, keep moving, I will continue trying. This course really gives strong fundamentals, it shows you the how and why of many things, so you learn to take decisions or understand what you do.
Andrei, thank you very much for this privilege and opportunity to learn from and with you!!! (I loved the AMA video too) And of course, I already have other courses already paid and waiting for me to start, because this is just my first but not my last course with Udemy/ZTM. Love you!!!

I’ve had a lot of previous JavaScript knowledge and used it for more than a decade as a web developer, but I never actually learned the foundations.
I could easily combine some code found on the web with a few lines of my own and make it a working script for a client, but I’d have quite a problem if I had to explain to someone how it actually works, what’s exactly happening where and why. This course won’t make you some omnipotent master of JS but most definitely it will make you understand what’s under the hood. And next time you’ll be writing js code, you’ll be able to make much better and informed decisions about solutions and techniques you should use.

This lecture helps a lot!!
Thanks Andre! see you next lecture!
you are greate developer instructor!

This course is simply great!. The key differentiator for me is the roadmap with all the fundamental knowledge that goes beyond programming and it is common to all programming languages. Coding is just syntax but learning what is really going on under the hood made a huge difference for me. This is the first online course where the instructor paints a clear path from the beginning to the end and defines all the topics that are needed to learn including fundamentals. I am lucky that I picked up this course. I thank you Andrei so much for your dedication and hard work preparing all these courses. They are simply great!
