Sergey Sharonov

Very good coverage of intermediate and advanced JS topics, including latest ES standards, with lots of bonus material and exercises. I liked the way Andrei writes codes live, make small mistakes and fixes them on the fly explaining any tricky parts.

Ludolf Pretorius

Andrei breaks down concepts in such a way that it's easy for anyone to understand. The content is very thorough and includes topics that I have struggled to find good documentation on. I feel confident in my level as a developer because of this course.

Mark Anthony Servanda

I've never been so motivated to learn more about JavaScript and web development in general since I started this course. I've been coding for years and missing some important concepts and best practices which this course helped me to internalize.

James Whitney

This course is fantastic and has definitely made me a better and more confident JavaScript developer. Andrei is a great instructor and I would recommend this course to anyone looking to gain a deeper understanding the language.

James Whitney

This course was so great. Thanks to this course, I got a job! I also got a better understanding of Javascript and much more. I really thank you Andrei, you made me a wiser and more confident developer.

Eduardo Baños

I took this after Andrei's Complete Web Developer. This course made me such a better developer, who understands programming and JavaScript concepts so much better. I'm glad I took this course. The job offers are already starting to arrive :)
