Array shift() in JavaScript – onlinecode

In this post, we will give you information about Array shift() in JavaScript – onlinecode. Here we will give you detail about Array shift() in JavaScript – onlinecode And how to use it also give you a demo for it if it is necessary.

The shift() function removes the first element from an array and returns the removed element.
As a result, the length of the array changes as well.

const array = [1, 2, 3, 4, 5];
array.shift(); // 1
array; // 2,3,4,5

If the array is empty, shift() will return undefined and not modify the array.

const array = [];
array.shift(); // undefined

shift(), in combination with push(), can be used to make an array act like a queue as shown below.

const array = [];

function next(array) {
  return array.shift();
}

function enqueue(array, val) {
  array.push(val);
}

enqueue('First');
enqueue('Second');

next(); // 'First'
array; // ['Second']
next(); // 'Second'
