Array.pop Redirect 1


The pop() method removes the last element from an array and returns that element.




The pop method removes the last element from an array and returns that value to the caller.

pop is intentionally generic; this method can be called or applied to objects resembling arrays. Objects which do not contain a length property reflecting the last in a series of consecutive, zero-based numerical properties may not behave in any meaningful manner.

If you call pop() on an empty array, it returns an undefined value.


Example: Removing the last element of an array

The following code creates the myFish array containing four elements, then removes its last element.

var myFish = ["angel", "clown", "mandarin", "surgeon"];

console.log("myFish before: " + myFish);

var popped = myFish.pop();

console.log("myFish after: " + myFish);
console.log("Removed this element: " + popped);

This example displays the following:

myFish before: angel,clown,mandarin,surgeon
myFish after: angel,clown,mandarin
Removed this element: surgeon
