What will you learn in this “Mastering JavaScript Essentials 2021 Novice to Professional” course.

In short, you'll learn it all! Seriously, our goal is to make the most comprehensive JavaScript course out there - not filled with fluff, but filled with only the most actionable and latest tips and strategies. We'll be updating this course periodically to make sure we're covering any JavaScript evolution.

You'll start by creating your very first web page, and then move to a fancy IDE and deal with Visual Studio Code.

You'll then learn JavaScript basics to get started and write your very first JavaScript app. This includes adding comments, string and number data type, variables in JavaScript, variables naming conventions, JavaScript Boolean and undefined data type, and much more.

Once you understand intermediate JavaScript like multiple array, array inside an object, playing with inner HTML and more, then you will learn about JavaScript ES6, ES7, ES8 and the latest ES9 version. You will also learn object-oriented programming in JavaScript.

Make me to feel at home with JS

By Slawomir Lasota on 8/14/2023

I chose this course because I wanted to organize my knowledge of js. Yes, I did learn something new that I didn't know. It is not a course for complete beginners, because the author explains some things laconically and too quickly. On the other hand, this is not a course to become an expert. The presentation of asynchronous mechanisms is definitely missing.

By Ahmad Raza on 8/7/2022

Great experience with you

By Hassan on 2/1/2022

By Nishith Shetty on 1/12/2022
