JavaScript - How to remove the last element of an Array

In this tutorial, we are going to learn about how to remove the last element of an array in JavaScript.

Consider we have an array with 3 elements like this.

const fruits = ["apple", "banana", "grapes"];

Now, we need to remove the last element grapes from the above array.

Removing the last element

To remove the last element of an array, we can use the built-in pop() method in JavaScript.

Here is an example:

const fruits = ["apple", "banana", "grapes"];

fruits.pop();

console.log(fruits); // ["apple", "banana"]

Note: The pop() method also returns the removed element.

Similarly, we can also remove the last element of an array by using the splice() method with -1 as an argument.

const fruits = ["apple", "banana", "grapes"];

fruits.splice(-1);

console.log(fruits); //  ["apple", "banana"]
