array.pop( )

The value of the last element of array, which is also deleted.

Description

The pop( ) method deletes the last element of an array, reduces the array’s length by 1, and returns the value of the deleted element. Compare with the shift( ) method, which deletes the first element of an array.

Example

myList = new Array("one", "two", "three");
trace ("Now deleting " + myList.pop( ));  // myList is now: ["one", "two"]
