With my 25+ years of experience in the programming industry - I’ve put all my JavaScript knowledge and teaching experience in building this comprehensive course. I’ve made sure there’s everything required for freshers as well as experienced individuals. With that being said - I am working on a progressive course update plan where I’ll add new lectures from time to time because JavaScript is an ocean and I need to dive deep to bring out the best and the most precious questions/concepts pearls for you!

The course is based on my experience as a teacher with thousands of students across platforms like Udemy as well as my YouTube channel. It's packed with all sorts of real-world interview and assessment questions which are asked in IT development companies - all with the goal of giving you the best possible way of learning JavaScript in the simplest ways.

What's in the course?
