JavaScript is a general programming language. It was just a scripting language for web pages, but it has now evolved into a programming language that can be used for server-side programming, creating apps, and manipulating hardware. By itself, JavaScript has no I/O(input/output).
It depends on the software how JavaScript works. To clear things up, JavaScript needs a host environment to extend it’s functionality. The most popular kind of host environments are browsers. Browsers implement JavaScript in their own way. Of course, it wouldn’t make sense to have a dozen different versions of JavaScript. So, a company called ECMA standardized JavaScript and it tells how any host environment should set up JavaScript.
In the next couple of tutorials, you’ll how this standard works and you should be able to use JavaScript in almost any browser. We’ll go over things like garbage collection, HTML5 APIs, and even a little bit of AJAX. It’s pretty hard to cover everything, so I’ll only cover the things that are important to know. We’ll take a look at common problems and easy solutions. By the end of this tutorial, you’ll be a JavaScript expert!
