Convert JavaScript array into comma-separated list?

Answer»

The Number object is for integers, floating-point numbers, etc. Let us now see how to CREATE a Number object:

var VAL = new Number(10);

Let us now create an object with floating-point value:

var val = new Number(25.90);

An example here is to GET the value of the specified Number object. We are creating a Number object:

<html>    <head>       <title>JAVASCRIPT Number Object</title>    </head>    <BODY>       <script>          var val = new Number(25.90);          document.write("Value = " + val.valueOf());       </script>    </body> </html>

The output: 

Value = 25.9

Let us now create another Number object and represent it in String:

<html>    <head>       <title>JavaScript Number Object</title>    </head>    <body>       <script>          var val = new Number(40);          document.write("String: " + val.toString());       </script>    </body> </html>

The output:

String: 40
