Once upon a time there was internet. You know, a bunch of computers all connected by wires. One person on a computer can read documents from another person is computer using a language called HTML.

Each computer’s web browser can properly display these documents. Add CSS to the mix and you’ve got a beautifully-styled web page. It is important to note that neither HTML nor CSS are programming languages.

Back in back in 1995 a few people at Netscape started to wonder, “What if there was a way to write a computer program for the browser?”This way, when HTML and CSS gets sent from one computer to another you can also send over some programming.

JavaScript
JavaScript

This code would run in someone’s web browser and create an even better user experience. Thus JavaScript was born!You’re probably familiar with Twitter. They use a lot of JavaScript on their web page to do things. Such as opening up a tweet in a bigger window for instance Also, any of the actions below a tweet will trigger some JavaScript to be run.

If I click the star to favorite a tweet JavaScript will tell the server,”This tweet is now a favorite.”If I click on reply you can see the Java Script behavior at work yet again it focuses on the expanded reply box. All of this behavior is made possible by JavaScript It’s worth mentioning that Java is not JavaScript.They are two separate programming languages.

JavaScript is not just for programming in the browser, but on servers, game programming,databases, and even robots.Yeah, robots! We’re only limited by our imaginations.
