# Global matchAll in JavaScript regexes

The `matchAll` method returns all matches as an iterable object, each element of which contains an array of the match and its capturing groups. The method can only be called with the `g` modifier.

Let's look at an example. Let's say we have the following string:

`let str = '12 34 56';`

We find all pairs of numbers and split their numbers into capturing groups:

`let matches = str.matchAll(/(\d)(\d)/g);`

Let's go through the resulting iterable in a loop and display the found matches:

`for (let match of matches) { console.log(match); // [12, 1, 2], [34, 3, 4], [56, 5, 6] }`

Given the following string:

`let str = '12:37 15:48 17:59';`

Find in it all substrings with the time and for each found put the hours and minutes into capturing groups.

Given a string:

`let str = 'site.ru sss site.com zzz site.net';`

Get an array of domain names from this string, put the domain name and its zone in different capturing groups in this array.
