Returning a string by adding all elements of an array by toString

Javascript toString object can connect all elements of an array and return as a string. This way we an use toString to display all elements of the array. This object toString uses commas as separators while adding all the elements.

If you want to specify your own delimiter other than commas then you can use array join function

Let us see this example on how to use toString function.

<script type="text/javascript">
var scripts = new Array();
scripts[0] = "PHP";
scripts[1] = "ASP";
scripts[2] = "JavaScript";
scripts[3] = "HTML";
document.write(scripts.toString());

</script>
