Fortunately, we live in an era of global connectivity and access to many resources. Thanks to the Internet and people who enjoy sharing content, you can find almost everything you need to learn, and for free.

Free tutorials, books and courses are easily found without spending too much. So if you want to learn about mobile development, databases, machine learning, cloud computing or any programming language you want, knowledge is just a couple of clicks away.

But if you are interested in web development, you should learn JavaScript. And there are many websites with free JavaScript tutorials that you can use for free. Let's review the main and most prominent ones.

Why do you need to learn JavaScript?

You can work in a Java-based web application and use Servlet and JSP for server-side scripting, but it is better to use jQuery and JavaScript for client-side scripting.

The point is that you may find an excess of information about this programming language out there. Most of it will be of little use and only very little will serve you.

Here are some useful resources if you want to learn JavaScript online for free. Our list includes official resources, interactive websites, good books and others. You will be able to take your code writing skills to the next level with them.
