BASIC INTRODUCTION OF JAVASRIPT
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's 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. 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 JavaScript 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. Are you excited yet? To get started — if you're
new to these parts —please take a moment to play through our free TECH BRAIN BD
tutorial on www.techbrainbd.com.

world of JavaScript. We hope you enjoy your stay.
