valueOf method to get all elements of JavaScript array

valueOf() : displaying elements

<script>
var scripts = new Array();
scripts[0] = "PHP";
scripts[1] = "ASP";
scripts[2] = "JavaScript";
scripts[3] = "HTML";

document.write(scripts.valueOf());
</script>

PHP,ASP,JavaScript,HTML

We can get all elements of an array by using valueOf(). The elements will be separated by comma. These are the primitive values of the array.

We can add another array to this

<script type="text/javascript">
servers= new Array('Apache', 'IIS');

var scripts = new Array();
scripts[0] = "PHP";
scripts[1] = "ASP";
scripts[2] = "JavaScript";
scripts[3] = "HTML";
scripts[4] = servers;
document.write(scripts.valueOf());

</script>

Output is here

PHP,ASP,JavaScript,HTML,Apache,IIS
