The join() method is used to put all the elements of an array into a string.
The elements will be separated by a specified separator.

| separator | Optional. Specifies the separator to be used |

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:
Jani,Hege,Stale
Jani.Hege.Stale |
