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
.
