In this article, we would like to show you how to get substring by regex in JavaScript​​​​​​.

Quick solution:

const result = text.match(regex);

 

Practical example

In this example, we use match() method with a regular expression to get the 'value' from the text.

// ONLINE-RUNNER:browser;

const text = 'Example value...';
const regex = /value/;

const result = text.match(regex);

if (result) {
	console.log(result[0]);  // 'value'
}
