INTRO TO JAVASCRIPT
Javascript is a scripting language that you can embed in HTML and execute in your browser. Javascript can perform features that HTML can not. Javascript is handled by the latest versions of browsers (i.e. Netscape, MSIE, Firefox).
STRUCTURE:
<SCRIPT LANGUAGE="Javascript">
<!-- This is a commentHere goes the Javascript
//-->
</SCRIPT>Browsers ignore <SCRIPT> tag and comment delimiters <!-- -->
Javascript can go almost anywhere, however, a common practice is to place common functions and global variables in the <HEAD> </HEAD> and call their functionality in <BODY></BODY>.
