How to get last n characters of a string in JavaScript

In this tutorial, we are going to learn about how to get the last n characters of a string in JavaScript.

Consider, we have a string like this:

const name = "Bentley";

Getting the last n characters

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

-n is the number of characters we need to get from the end of a string.

Here is an example, that gets the last 4 characters of a string:

const name = "Bentley";

const lastFour =  name.slice(-4)

console.log(lastFour); // "tley"

Similarly, we can also get the last n characters of a string by using the substring() method.

const name = "Bentley";

const lastFour =  name.substring(name.length-4);

console.log(lastFour); // "tley"

In the above code, the substring() method begins the extraction of a string after the name.length - 4.
