In Javascript, the matchAll() method is used to return all the iterators matching the reference string against a regex (regular expression). An important use of the matchAll() method is that it can be used to capture groups with the /g flag giving it an advantage over the match() method which ignores capturing groups with the /g flag.
Syntax:
str.matchAll(Regexp)
Parameter:
- Regexp: It is simply a regular expression object. The RegExp object must include the /g flag, else an TypeError is thrown.
Return value: It is an iterator.
Example :
Javascript
function myFunction() {         //Regular expression with the /g flag     const regex = /e(xam)(ple(\d?))/g;     //Reference string     const str = 'example1example2example3';           //Using matchAll() method     const array = [...str.matchAll(regex)];           console.log(array[0]);     console.log(array[1]);     console.log(array[2]); }  myFunction(); |
