How to get first element of an array in JavaScript?

In this tutorial, we are going to learn about two different ways to get the first element of an 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 any given 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.
