<titleTypes of Variable</title>
</head>
<body>
<script language="javascript">
var intval=30;
var floatval=8.50;
var stringval="Hello";
var booleanval=true;
document.write("Integer value = " + intval + "<br>");
document.write("Float value = " + floatval + "<br>");
document.write("String value = " + stringval + "<br>");
document.write("Boolean value = " + booleanval + "<br>");
</script>
</body>
</html>
OUTPUT
Integer value = 30
Float value = 8.5
String value = Hello
Boolean value = true
