    Array.prototype.pop()

    Summary

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

    Syntax

    arr.pop()

    Description

    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.

    Examples

    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', 'sturgeon'];
    
    console.log(myFish); // ['angel', 'clown', 'mandarin', 'sturgeon']
    
    var popped = myFish.pop();
    
    console.log(myFish); // ['angel', 'clown', 'mandarin' ] 
    
    console.log(popped); // 'sturgeon'
