Parsing JSON in JavaScript PRO

There are many cases in which we need to parse JSON data our code receives. When writing our code in JavaScript parsing the JSON data is fairly simple. We just need to invoke the parse() function on the JSON object, as in the following code sample. The JSON object is available in most modern web browsers.

<!DOCTYPE html>
<html>
<head>
    <title>JSON Parsing</title>
</head>
<body>
<script type="text/javascript">
    var data = '{"firstname":"haim","lastname":"michael"}';
    var ob = JSON.parse(data);
    document.writeln("<br>firstname:"+ob.firstname);
    document.writeln("<br>lastname:"+ob.lastname);
</script>
</body>
</html>

The following video clip overviews this code sample, shows its execution and explains it step by step.
