Luckily for us, we are living in an era of global connectivity and access to lots of resources. Thanks to the Internet and people who likes to share, you might find almost all that you need to learn.
Free tutorials, books and courses are easily available without spending too much. So if you want to learn mobile development, databases, machine learning, cloud computing, or whatever computer languages 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 lots of websites with free JavaScript tutorials that you can use for free. So if you have a good internet connection, that’s all you need to take advantage of these online resources.
Why do you need to learn JavaScript?
You can work on Java-based web application and use Servlet and JSP to server-side scripting, but it’s nicer to use jQuery and JavaScript for client-side scripting.
The thing is that out there you may find too much information about this programming language. Most of it will be extremely useful, some, just rubbish.
Therefore, here we present some useful resources if you want to learn JavaScript online for free. Our list includes official resources, interactive websites, good books, and others. So take your coding to the next level by using them.
