pop Method (Array) (JavaScript)

Removes the last element from an array and returns it.

Syntax

  
arrayObj.pop( )  

Remarks

The push and pop methods enable you to simulate a stack, which uses the principle of last in, first out (LIFO) to store data.

The required arrayObj reference is an Array object.

If the array is empty, undefined is returned.

Example

The following example illustrates the use of the pop method.

var number;  
var my_array = new Array();  
  
my_array.push (5, 6, 7);  
my_array.push (8, 9);  
  
number = my_array.pop();  
while (number != undefined)  
   {  
   document.write (number + " ");  
   number = my_array.pop();  
   }  
  
// Output: 9 8 7 6 5
