The code sample shows how to declare variables in a javascript script. This is in fact a html file that contains javascript code.


<html>
<head>
<title>Declaring Variables in JavaScript</title>
<script language="javascript">
var myName; //variable myName is declared
myName="Kapil"; // myName is assigned a value. also called definition
document.write(myName);
document.write("<br />");
myName="Dhawan"; // assign a new value to myName. the older value is erased.
document.write(myName);
</script&RT;
</head>
<body>
</body>
</html>

The results of this example could easily be seen by copying the code into notepad, saving it as a file with .html extension and opening it in a web browser.
