How to get first n characters of a string in JavaScript

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

Consider, we have a string like this:

const name = "King Kong";

Getting the first n characters

To access the first n characters of a string in JavaScript, we can use the built-in slice() method by passing 0, n as an arguments to it.

n is the number of characters we need to get from a string, 0 is the first character index (that is start position).

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

const name = "King Kong";

const firstFour =  name.slice(0, 4)

console.log(firstFour); // "King"

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

const name = "King Kong";

const firstFour =  name.substring(0, 4)

console.log(firstFour); // "King"
