In this section, we will learn what the Array unshift() method is and how to use it in JavaScript.

JavaScript Arrays unshift() Method

We can use the `unshift()` method when we want to add new elements to the beginning of an array.

Note: if you want to add elements to the end of an array, use the Array push() method.

Array unshift() Syntax:

Array unshift() Method Parameters:

The arguments to the `unshift()` method are the elements that want to add to the target array.

Array unshift() Method Return Value:

The return value of this method is the new length of the target array.

Example: JavaScript add item to beginning of array

const arr = ["Tesla","Google"];

const length = arr.unshift("Microsoft","Amazon","Facebook","Twitter");

console.log(`The new length of the array is: ${length}`);

console.log(arr);

Output:

["Microsoft", "Amazon", "Facebook", "Twitter", "Tesla", "Google"]
