reverse Method


function reverse() : Array

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.

The following example illustrates the use of the reverse method.

В	Copy Code
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. }

Copy Code

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.
}
