How to check if the string ends with another in JavaScript

In this tutorial, we are going to learn how to check if the string ends with another substring in JavaScript.

Checking string ends with another

To check if a string ends with another, we can use the built-in endsWith() method in JavaScript.

The endsWith() method takes the search string as an argument and returns true if a search string is found; otherwise, it returns false.

Here is an example:

const str = 'How are you';
console.log(str.endsWith('you'));

Output:

true

We can also set the length of a string by passing the second argument to endsWith() method, by default length points to string.length property value.

In this example, we are checking if a string ends with are substring, by assumming the string contains only 7 characters.

const str = 'How are you';
console.log(str.endsWith('are', 7));

Output:

true

Note: The endsWith() method is case-sensitive.
