The Array pop() method is used to remove the last element from an array and returns that element. This method changes the length of the array.

Syntax

arr.pop()

Return value - The removed element from the array; undefined if the array is empty.

JavaScript Array.pop() Method Examples

Example 1: Simple Array pop() method example

var progLangs = ['C', 'C++', 'Java', 'PHP', 'Python'];

console.log(progLangs.pop());
// expected output: "Python"

console.log(progLangs);
// expected ["C", "C++", "Java", "PHP"]

progLangs.pop();

console.log(progLangs);
// expected ["C", "C++", "Java"]

Example 1: Removing the last element of an array

The following code creates the progLangs array containing five elements, then removes its last element.

var progLangs = ['C', 'C++', 'Java', 'PHP', 'Python'];

var popped = progLangs.pop();

console.log(progLangs);

console.log(popped);

Output:

["C", "C++", "Java", "PHP"]
Python

Example 3: Using apply( ) or call ( ) on array-like objects

The following code creates the myFish array-like object containing four elements and a length parameter, then removes its last element and decrements the length parameter.

var myFish = {0:'angel', 1:'clown', 2:'mandarin', 3:'sturgeon', length: 4};

var popped = Array.prototype.pop.call(myFish); //same syntax for using apply( )

console.log(myFish); // {0:'angel', 1:'clown', 2:'mandarin', length: 3} 

console.log(popped); // 'sturgeon'
