# Global match in JavaScript regexes

The `match` method, invoked with the `g` modifier, returns all found matches as an array. Let's look at examples.

## Example

Let's obtain an array of substrings consisting of the letters `'a'`:

`let str = 'a aa aaa aaaa'; let res = str.match(/a+/g);`

As a result, the following will be written to the variable:

`['a', 'aa', 'aaa', 'aaaa']`

## Example

Let's get an array of numbers:

`let str = '1 23 456 789'; let res = str.match(/\d+/g);`

As a result, the following will be written to the variable:

`['1', '23', '456', '789']`

## Example

Let's get an array of all digits:

`let str = '1 23 456 789'; let res = str.match(/\d/g);`

As a result, the following will be written to the variable:

`['1', '2', '3', '4', '5', '6', '7', '8', '9']`

## Practical tasks

Given a string:

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

Get an array of domain names from this string.

Given a string:

`let str = 'a1b c34d x567z';`

Find the sum of all numbers in this string.
