Excellent Free Tutorials to Learn JavaScript

Last Updated on November 23, 2023

JavaScript is possibly one of the easiest language to get up and running with. But to truly master the language requires a firm foundation of its intricacies.

JavaScript is an interpreted, prototype-based, scripting computer programming language. It came to popular attention as a simple client-side scripting tool, interacting with the user using forms and controlling the web browser, and remains a front-end language for web applications.

JavaScript features dynamic types, it’s weakly typed, supports the structured programming syntax from C, uses prototypes instead of classes for inheritance, and copies many names and naming conventions from Java. It also borrows design principles from Scheme and Self, as well as concepts and syntax idioms such as C-style procedural roots.

Here’s our recommended tutorials to learn JavaScript. If you’re looking for free JavaScript programming books, check here.

I’ve been working through No.8, “The Modern JavaScript Tutorial” by Ilya Kantor – it’s pretty good, broken down into bite-sized lessons, and provides excellent explanations. You can easily get through the fundamentals – at least the first 20 lessons or so – just using the Chrome debugger, so it is easy to get started quickly without installing anything special to see if it suits you.

Continues right through into intermediate and advanced topics. There’s 93 lessons and counting!

Highly recommended.
