<html>
<head>
<title>Hello World</title>
<script language="JavaScript" type="text/javascript">
// x represented in binary as 00000101
var x = 5;
// y represented in binary as 00001001
var y = 9;
result = x & y;
document.write(result + "<br>");
result = x | y;
document.write(result + "<br>");
result = x ^ y;
document.write(result + "<br>");
result = ~4294967292;
document.write(result + "<br>");
result = y << 2;
document.write(result + "<br>");
result = y >> 2;
document.write(result + "<br>");
</script>
</head>
<body>

</html>
When you load this file into your browser you will get the following values:
There's nothing special about this example because we have explained the bitwise operators in the above section.
