Learn JavaScript for Free: 10 Online Resources For Every Level of Expertise

By: Daniel Weiss

JavaScript is the programming language of the web. It isn’t necessarily the easiest programming language to learn, but if you’re interested in building web applications or becoming a developer, JavaScript courses will help you even if you are an advanced programmer.

Once considered a strictly client-side language, Node.js now allows JavaScript to run both the frontend and the backend. That yields a lot of benefits, both for learning web development and in the job market.

But which JavaScript resource is for you? We’ve compiled a list of the best free JavaScript resources to guide you through your learning journey, whether you’re just starting out or you already know how to use booleans, strings and data structures. With the tutorials and videos from our modern JavaScript "code school," you’ll find the perfect resource to take you to the next level.

This intro free course is similar to CodeSchool’s JavaScript Courses. This is a pre-beginner JavaScript tutorial that will help you get familiarized with programming language like basic functions, libraries, data structures and all other JavaScript fundamentals.

This course is so easy that even your pet can start coding in no time.


You’ve decided that learning JavaScript will be a beneficial and possibly fun endeavor.

Codecademy’s Intro to JavaScript Track

If 0 is a pure beginner and 100 is a professional full-stack developer, 15-20 hours of Codecademy’s JavaScript track will take you all the way to 6.8. In all seriousness, Codecademy’s step-by-step tutorial system is great for an introduction to programming in JavaScript. You will learn functions, loops, data structures and many other data types. They also have other online courses for many other languages like CSS, HTML, SQL and PYTHON.

Treehouse’s JavaScript Foundations

It’s not technically free, but Treehouse offers a multi-platform learning experience that includes videos, coding tutorials and quizzes. If you’re looking to gain a solid foundation in a short amount of time, the 14-day free trial might suit your needs in becoming a web developer. The benefits of this course will help you understand where JavaScript is used, basic concepts for variables, data types and conditional statements, and how to troubleshoot programming problems.

MDN JavaScript

Published by Mozilla, this site incorporates tutorials and lessons in addition to a glossary of JavaScript functions. This could be a good tab to have open next time you’re attempting those codewars.com challenges. MDN JavaScript is offered in many other languages and it's a great refresher of the JavaScript programming language. For non-expert programmers, you can use JavaScript Garden to avoid common mistakes and bugs.

Learn JS

Learn-JS.org is intended for everyone who wishes to learn the JavaScript programming language. This website is an interactive JavaScript tutorial where you can run free JavaScript code directly from the web browser. You are able to try JavaScript without even installing it. Here you can learn the basics, take advance tutorials or help others to learn by contributing with tutorials.

Khan Academy  

This a non-profit organization that wants to provide a free, world-class code education to everyone. Khan Academy is a good learning platform where you can find tutorials not only for computer programming but for other subjects like math, arts, economics and finance. They have a JavaScript tutorial that can help you work with DOM events with jQuery, used for making animations and effects on a webpage. As their motto states, "You can learn anything. For free. For everyone. Forever."

Fullstack Academy's Bootcamp Prep Online

This workshop-based video course has 40 hours of content and teaches all the fundamentals of JavaScript. Besides instruction on core concepts, it also reviews a large number of coding challenges, which are arranged by level of increasing difficulty, and each is followed by an instructor tutorial. If you are searching for some advanced tutorials, Bootcamp Prep is a more demanding course for those who really are committed to attending to Fullstack Academy or other elite coding schools. 


CoderByte challenges are an excellent resource, especially if you want to apply to a more selective coding bootcamp as part of a career transition. These coding problems are a pretty accurate representation of the challenges on the Fullstack application’s technical coding assessment. Keep in mind that the beginner-level challenges are still pretty hard. If you find these too difficult, review the beginner resources listed above or consider attending an in-person coding class.

Eloquent JavaScript by Marijn Haverbeke

Intermediate level programmers will benefit from the first four chapters of this book, which include an overview of JavaScript syntax, functionality, loops and arrays and last but not least atoms of the data structures (numbers, booleans and strings).

The rest of the chapters are for advanced programmers where you can find more about HTTP and Forms, the difference between POST and GET requests, and Node.js, which is a back-end JavaScript technology that executes code server-side.
