Submitted by Pankaj Singh, on October 12, 2018

Example:

Here, we are defining a JavaScript function named show() which has two arguments id and name and calling the function, with 1) both arguments, 2) one argument and 3) no argument.

Code:

<html lang="en">
<head>
    <script>
        function show(id,name){
            document.write("Your name is <b>"+name+"</b> and your id is <b>"+id+"</b><br /><br />");
        }
    </script>
</head>
<body>
    <script>
        show(12,"pankaj");
        show(12);
        show();
    </script>
</body>
</html>
