arr.pop()
The removed element from the array; {{jsxref("undefined")}} if the array is empty.
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 {{jsxref("Function.call", "called", "", 1)}} or {{jsxref("Function.apply", "applied", "", 1)}} 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 {{jsxref("undefined")}}.
{{jsxref("Array.prototype.shift()")}} has similar behavior to pop
, but applied to the first element in an array.
The following code creates the myFish
array containing four elements, then removes its last element.
var myFish = ['angel', 'clown', 'mandarin', 'sturgeon']; var popped = myFish.pop(); console.log(myFish); // ['angel', 'clown', 'mandarin' ] console.log(popped); // 'sturgeon'
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'
