JavaScript Reverse () method
In this case, we'll create an array and then reverse the order of its elements:
<script type= "Text/javascript" > var arr = new Array (3) arr[0] = "George" arr[1] = "John" arr[2] = "Thomas" docu Ment.write (arr + "") document.write (Arr.reverse ()) </script>
[Ctrl + A All SELECT Note: If the need to introduce external JS need to refresh to perform]

Output:
Copy Code code as follows:

George,john,thomas
Thomas,john,george
