How to check if the string starts with another in JavaScript

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

Checking string starts with another

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

The startsWith() 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 = 'this is my name'

console.log(str.startsWith('this'));

Output:

true

By default, the string searching starts from position 0. We can also change its position by passing the second argument.

const str = 'this is my name';

console.log(str.startsWith('my',8));

Output:

true

Note: The above method is case-sensitive.
