How to get first element of a array in JavaScript

In this tutorial, we are going to learn about two different ways to get the first element of a array in JavaScript.

Consider we have an array with 3 elements like this.

const arr = ['lol','ball','doll']

Now, we need to get the first element 'lol' from the above array.

First way: Using element index

We can get the first element of an array by using its element index.

Example:

const arr = ['lol','ball','doll'];

console.log(arr[0]); // 'lol'

Note: In JavaScript, the array index starts from 0 so that the first element index is 0.

Second way: Using the slice method

In es6, we have a slice( ) method, if we pass 0,1 as arguments to the slice() method we can get the first element of an array.

Example:

const arr = ['lol','ball','doll']

console.log(...arr.slice(0,1)); // 'lol'

Note: The slice() method doesn’t modify your original array.
