# Features of the Cyrillic alphabet in regex in JavaScript

Cyrillic characters are not included in the `\w` group. To get them, you need to use a group in square brackets, like this: `[а-я]`. But even with this group, there is a problem - the letter `'ё'` will not be included here. To enable it, you need to do this: `[а-яё]`.

Given a string:

`let str = 'wйw wяw wёw wqw';`

Write a regex that will find strings according to the pattern: letters `'w'` are at the edges, and a Cyrillic letter is between them.

Given a string:

`let str = 'ааа ббб ёёё ззз ййй ААА БББ ЁЁЁ ЗЗЗ ЙЙЙ';`

Write a regex that will find all words according to the pattern: any Cyrillic letter any number of times.
