What is match() Method in JavaScript ?

JavaScript String match() method is an inbuilt function in JavaScript used to search a string for a match against any regular expression. It returns an array containing the matches found, or null if no matches are found.

Syntax:

string.match(regExp);

Parameters:

• regExp: (i.e. regular expression) which will compare with the given string. 

Example: Here, the match() method is called on the str string with the regular expression /fox/g as its argument. This regular expression searches for the word “fox” within the string. Since “fox” is present in the string, the method returns an array ["fox"], which contains the match found.

Javascript

const str = "The quick brown fox jumps over the lazy dog";
const matches = str.match(/fox/g);

console.log(matches); // Output: ["fox"]

Output

[ 'fox' ]
