How to get last n elements of an array in JavaScript

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

Consider, we have an array like this:

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

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

n is the number of elements, - is used to access the elements at end of an array.

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

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

const lastTwo = cars.slice(-2);

console.log(lastTwo); // ["volvo", "skoda"]

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

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

const lastThree = cars.slice(-3);

console.log(lastThree); // ["bmw", "volvo", "skoda"]
