The previous two posts presented free outlets where you can start learning HTML/CSS and jQuery, this post will present free outlets for beginners to learn JavaScript. What’s common between HTML/CSS, jQuery and JavaScript is that they’re all client side web development languages, which means that the code is compiled on the client computer not on the server.
JavaScript has many uses in web development, one of the uses of JavaScript is processing a form being filled by a user before sending it to the server, so you’re sure that mandatory fields are filled otherwise an error message appears to the user, it’s many other usages that you’ll know while you’re learning. Finally, you should know that JavaScript has nothing to do with Java both are separate programming languages.
