What is JavaScript?

hey please friends tell me that what is JavaScript?
And give some examples of Javascripts. Like give some url which contain javascript.

well you could try typing the following into your browser (firefox) URL:

javascript: document.void(alert('test'));

and then pressing return.

JavaScript was originally designed by good old NetScape.. back in the days
JavaScript is an object scripting language that you can use in within your web pages. It's a client side language.

Contrary to misconception, JavaScript is not Java! These two languages are not at all the same

To create a simple example containing some JavaScript, copy the following and save it as example.html. Then place this on your site and see what happens...

<html>
<head>My First JavaScript</head>
<body>
This page contains my first example of JavaScript

<script type="text/javascript">
document.write("This message is written by JavaScript");
</script>

<script type="text/javascript">
alert('hello world');
</script>

</body>
</html>

You've just written you first bit of script in JavaScript.

Its quite common to call the JavaScript by placing an external reference line from the html head section, this makes the script more global, calling it from other pages, and also keeps the html content cleaner

and example:

<html><head><title>My Second JavaScript</title>
<script type="text/javascript" src="myScrip/helloWorld.js"></script>
</head>
<body>
This page contains my second example of JavaScript
<script type="text/javascript">doFunction();</script>
</body></html>

where doFunction will be defined within the external helloWorld.js JavaScript

What exactly is Javascript?:
Javascript is a programming language that is used to make web pages interactive. It runs on your visitor's computer and so does not require constant downloads from your web site

Javascript is an online coding language for websites, you can use it to interact with a server and variables, it's good for some basic forms and math

I think that Javascript is a programming language that is used to make web pages interactive. It runs on your visitor's computer and so does not require constant downloads from your web site.

Example:-

Everyone's first script

hello.html

<HTML>
<HEAD>
<TITLE>Barely a script at all</TITLE>
</HEAD>
<BODY BGCOLOR=WHITE>
<H1>
<SCRIPT LANGUAGE="JAVASCRIPT">
document.write("Hello, World!")
</SCRIPT>
</H1>
</BODY>
</HTML>

I always use to tell people that javascript is like more advanced HTML. Of course with HTML5 coming out I suppose that wouldn't really be true any more.

By the knowledge of Javascript the web owner would do to himself and to the browsers a lot of good in the sense that he allows the visitor to learn the script then and there.
