JavaScript - split string into segments of n characters

In this article, we would like to show you how to split a string into segments of n characters in JavaScript.

Quick solution:

const text = 'abcdefghijklmnop';
const result = text.match(/.{1,3}/g); // [ 'abc', 'def', 'ghi', 'jkl', 'mno', 'p' ]

Practical example

In this example, we use /.{1,3}/g split string into chunks of 3 characters.

// ONLINE-RUNNER:browser;

const text = 'abcdefghijklmnop';
const regex = /.{1,3}/g;

const result = text.match(regex);

if (result) {
    console.log(JSON.stringify(result)); // [ 'abc', 'def', 'ghi', 'jkl', 'mno', 'p' ]
}

Note:

The last chunk's length may differ depending on the number of characters left.
