<html>
<head>
<script language="JavaScript">
function datatype()
{
}
function check(arg)
{
document.write(typeof(arg));
}
var data=new datatype();
</script>
</head>
<body>
<input type="button" onclick="(data)" value="Object">
<input type="button" onclick="check(5)" value="Number">
<input type="button" onclick="check('Hello')" value="String">
</body>
</html>
