JavaScript - get substring after word

In this article, we would like to show you how to get substring after word in JavaScript.

1. Using slice() method

In this example, we use indexOf() method to get the index of a word substring. Then we use slice() to get the substring from index + length index to the end of the text string.

// ONLINE-RUNNER:browser;

const text = 'This is example text...';
const word = 'example';

const index = text.indexOf(word);   // 8
const length = word.length;			// 7

const result = text.slice(index + length);

console.log(result);  // ' text...'

2. Using split() with pop() method

In this example, we split the text by the word and get the part after it using pop() method.

// ONLINE-RUNNER:browser;

const text = 'This is example text...';
const word = 'example';

const array = text.split(word);  // ['This is ', ' text...']
const result = array.pop();      // ' text...'

console.log(result);  // ' text...'
