Example

In this example we will create an array, and then put all the elements in a string:

<script type="text/javascript">
var arr = new Array(3);
arr[0] = "Jani";
arr[1] = "Hege";
arr[2] = "Stale";
document.write(arr.join() + "<br />");
document.write(arr.join("."));
</script>

The output of the code above will be:
