Add an Element at the Beginning of Array in JavaScript

In this article, we are going to add an item at the beginning of an array. To do this, we will use the splice() method.

The splice() method takes a few arguments. To add at the first position, we need to use 0 as the first argument:

const colors = ['2', '3', '4', '5']

colors.splice(0, 0, '1')


Console log output:

0: "1"
1: "2"
2: "3"
3: "4"
4: "5"
length: 5__proto__: Array(0)
That’s it. Thanks for reading. ?
