Hello devs, If you want to learn JavaScript in 2023 online by yourself and looking for free resources like books, websites, and tutorials, then you have come to the right place.

Earlier, I have shared the best paid JavaScript online courses to learn JavaScript in depth and In this article, I am going to share best free online courses you can join to learn JavaScript in depth by yourself, on your own schedule, and at your own place.

A lot of people are learning JavaScript, and the number is only increasing with each passing day, and why not? It's the #1 web development language. It got tons of useful frameworks and libraries like Angular, React Node.js, and jQuery, which makes web development really easy.

If you are looking for a job or starting your own website, learning JavaScript is the right decision. In today's world, I highly encourage people to learn to code and at least know to build a web application and mobile application on their own, and by learning JavaScript, you can hit these two birds in one stone.

Yes, you can also develop a mobile application using JavaScript. If you don't, ReactNative is a JavaScript library, which allows you to develop a mobile app for Android and iOS devices like the iPhone and iPad in JavaScript.

Now, the big question is which courses you should choose to learn JavaScript? There are tons of choices available in terms of books, tutorials, paid courses, and free classes.

There are even websites you can use to learn JavaScript interactively. You might want to check out them in my earlier post about 5 sites to learn JavaScript.

In this article, I will share my list of some of the best courses to learn JavaScript in 2023, and that too for free. Though you can start learning JavaScript the way you want, my suggestion is to start with fundamentals, learn the JavaScript language before learning any framework or library.

While I have shared a lot of useful free JavaScript courses, I also highly recommend you check out The Complete JavaScript Course - Build Real Projects! course by Jonas Schmedtmann on Udemy. It's one of the most up-to-date and hands-on courses to learn JavaScript for beginners.

If you don't mind spending a few bucks learning a valuable skill like JavaScript then this is the best course to invest your money and time. It's also very affordable and you can buy it for just $10 on Udemy sales.

7 Best Free Online Courses to Learn JavaScript in 2023

Once you have a good understanding of JavaScript syntax, rules, and coding style and can create scripts by yourself, you can explore the fancy world of Angular, React, Node.js, jQuery, and other JavaScript libraries.

With that idea, here are my top 7 free online courses from Udemy and Pluralsight to learn JavaScript fundamentals

1. JavaScript Essentials [Free]

This is a basic course to learn the JavaScript programming language. In this course, you will learn all the basics of JavaScript language like primitive types, arrays, functions, operators, objects like a window, DOM, and much more.

You'll also learn how JavaScript works, some essential APIs, and in the end, you will develop a mini JavaScript project by applying the knowledge you have gained in this free JavaScript course.

The course is ideal for anyone starting with JavaScript from scratch but has some programming experience, but don't worry; if you are new to programming and just started with JavaScript, then also you can take this course as it perfect for beginners.

2. Learn to Program in JavaScript: Beginner to Pro [Free]

One of the biggest issues with programming JavaScript is that many programmers coming from C, C++, and Java start coding in JavaScript without first understanding the programming language, its syntax, style, and paradigm.

This free course tries to fill that gap. It's an introductory to intermediate level JavaScript course, which will not only tell you about language syntax, language paradigm, and how JavaScript works but also explains functional programming and how you can write useful code in JavaScript.

You will also learn about Objects in Java, as JavaScript also supports object-oriented programming. The course also touches base on AJAX and HTML 5, two key technology for JavaScript developers.

Once you have gone through this course, you would have sufficient knowledge to write JavaScript code and learn JavaScript frameworks like Angular, React, or jQuery.

3. Introduction to JavaScript @ Codecademy

If you are looking for an interactive tutorial to learn JavaScript this is the best free JavaScript tutorial you can get on internet. In one word, this is one of the best free JavaScript tutorials, and I have learned JavaScript from this site.

It is also one of the best platforms to learn new technologies online but probably the best website to learn JavaScript online.

Even though currently, Codecademy offers Java, Git, UNIX command line, and several other courses, it made its name by an interactive JavaScript course to learn online at your own pace.

You can gauge the popularity of this course by looking at the number of students enrolled, currently, 5M+, which is a very high number for any online FREE course.

You can sign up for this free JavaScript tutorial here.
