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.
