Getting the last element of an array in JavaScript

In this tutorial, we are going to learn about how to get 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 get the last element grapes from the above array.

Getting the last element

To get the last element of an array, we can use the square brackets [ ] syntax by passing an array.length-1 as an argument to it.

The array.length property returns the total number of elements in an array. If we subtract it with -1 we will get the last element index.

Here is an example:

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

const lastElement = arr[arr.length-1];

console.log(lastElement); // "grapes"

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

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

const lastElement = arr.slice(-1);

console.log(lastElement); // ["grapes"]
