1. Giving the user more control over the browser.
2. Detecting the user's browser and OS. The ability to detect the user's browser and OS allows your script to perform platform-dependent operations, if necessary.
3. Performing simple computations on the client side.
4. Validating the user's input.

JavaScript is client side scripting language. When you open a web page your web browser first downloads all the necessary files from the server to display that page correctly. Those necessary files are HTML, CSS, Images, Videos, etc and the JavaScript files too. After completing download the browser displays that page on its window and any script linked with it will run from the downloaded script file.

As JavaScript runs from the client computer its execution time is very short, almost instantaneous. Viewers can run JavaScript without being connected with the server as well.

JavaScript can do almost anything!

They go from changing the background color to passwords and even to games like RuneScape.

Important note:

When begining a JavaScript function, ALWAYS put it inbetween

<HEAD>

<SCRIPT language="JavaScript">

and

</SCRIPT>

</HEAD>

If that doesn't work then put the functions between:

<HEAD>

<SCRIPT language="JavaScript">



</SCRIPT>

</HEAD>
