How to get first n elements of an array in JavaScript

In this tutorial, we are going to learn about how to get the first n elements of an array in JavaScript.

Consider, we have an array like this:

const cars = ["benz", "bmw", "volvo", "skoda"];

To access the first n elements of an array, we can use the built-in slice() method by passing 0, n as an arguments to it.

n is the number of elements we need to get from an array, 0 is the first element index.

Here is an example, that gets the first 2 elements of an array:

const cars = ["benz", "bmw", "volvo", "skoda"];

const firstTwo = cars.slice(0, 2);

console.log(firstTwo); // ["benz", "bmw"]

Similarly, you can get first 3 three elements like this:

const cars = ["benz", "bmw", "volvo", "skoda"];

const firstThree = cars.slice(0, 3);

console.log(firstThree); // ["benz", "bmw", "volvo"]
