Why JavaScript Data Types are Dynamic?
JavaScript also has dynamic types. That would mean the same variable used for holding different data types in JavaScript.
Example
<html>
<head>
<script>
var val;
val = "Amit";
document.write("String: "+val);
val = 20;
document.write("<br>Number: "+val);
val = 40.90;
document.write("<br>Number with decimals: "+val);
</script>
</head>
<body>
</body>
</html>
