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:

javascriptlet str = '12 34 56';

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

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

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

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

javascriptlet str = '12:37 15:48 17:59';

javascriptlet str = 'site.ru sss site.com zzz site.net';
