reverse Method

Returns an Array object with the elements reversed.

function reverse() : Array

Remarks

The reverse method reverses the elements of an Array object in place. It does not create a new Array object during execution.

If the array is not contiguous, the reverse method creates elements in the array that fill the gaps in the array. Each of these created elements has the value undefined.

Example

The following example illustrates the use of the reverse method.

function ReverseDemo(){
   var a, l;                  //Declare variables.
   a = new Array(0,1,2,3,4);  //Create an array and populate it.
   l = a.reverse();           //Reverse the contents of the array.
   return(l);                 //Return the resulting array.
}
