Availability

JavaScript 1.1; JScript 2.0; ECMAScript v1

Synopsis

                  array.reverse( )

Description

The reverse( ) method of an Array object reverses the order of the elements of an array. It does this “in place” -- it rearranges the elements of the specified array, without creating a new array. If there are multiple references to array, the new order of the array elements is visible through all references.

Example

a = new Array(1, 2, 3);    // a[0] == 1, a[2] == 3;
a.reverse(  );             // Now a[0] == 3, a[2] == 1;
