JavaScript Regex: Remove text between parentheses, brackets and cyrillic character

Question

Would it be possible to change

(Test 1 / Test 2) [Test 3] Отдел / Here is title - subtitle (by Author) - 1234 (5678-9999), descriptions (best), more descriptions

to

Here is title - subtitle (1234) (descriptions)

using JavaScript with Regex?

Currently, I have to combine multiple replace functions, like below

let text = '(Test 1 / Test 2) [Test 3] Отдел / Here is title - subtitle (by Author) - 1234 (1234-4567), descriptions (best), more descriptions';

text = text
  .replace(/ *\([^) ]*\) */g, "")
  .replace(/ \([\s\S]*?\)/g, '')
  .replace(/[0-9`~!@#$%^&*()_|+\-=?;:'",.<>\{\}\[\]\\\/]/gi, '');

console.log(text);

But it doesn't working as expected. Anyone have any ideas?

Is the input string ***always*** in the same format, ie. are the parentheses, slashes, dashes etc. in the same place, in every instance? — Rory McCrossan, Jul 16 '21 at 10:41
And does output `(1234)` come from `1234` or first part of `(1234-4567)` — mplungjan, Jul 16 '21 at 10:43
for cyrillic: https://stackoverflow.com/questions/1716609/how-to-match-cyrillic-characters-with-a-regular-expression — GrafiCode, Jul 16 '21 at 10:43
And what is `(descriptions)` in the result supposed to be, based on `descriptions (best), more descriptions`? — CBroe, Jul 16 '21 at 10:44
But _which part_ of `descriptions (best), more descriptions`? — CBroe, Jul 16 '21 at 11:09
Please update the question with concrete step by step requirements: 1) remove substrings between `[` and `]`, 2) .... 3) wrap the part after/betwee with parentheses, etc. to make the question answerable. Right now, "Remove text between parentheses, brackets and cyrillic character" just warrants a `.replace(/$[^()]*$|\[[^\][]*]|[\u0400-\u04FF]+/g, '')` (like [here](https://regex101.com/r/wav6yX/1)), but it does not provide the expected output. — Wiktor Stribiżew, Jul 16 '21 at 12:50

Entering this as an answer to "prove" that it works ;)

But, as I said in comment, it's not pretty. There must be a better way.

Anyway, what it does is to consume (match) everything inside the first parenthesis pair with $[^)]*$. After that it matches everything up to / (inclusive) with [^/]*?\/\s* (made the first part there non greedy which it wasn't originally). Then it captures the title, up to (, with ([^(]*?)\s*$. After that it's time to match up to 1234. Done with [^)]*$\s*-\s*.

Time to capture 1234 with (\d+) (I'm assuming it's always a number, otherwise you need to replace it with something lik ([^)]*).

Math up to the description with \s*$[^)]*$,\s* and capture it with (.*?)\s\( (the \s\( is to not get it in the capture group).

Finally match the rest with .*$ (not really necessary, but... :)

Replace all this with $1 ($2) ($3) to get parentheses in the right places. Voila :D

let text = '(Test 1 / Test 2) [Test 3] Отдел / Here is title - subtitle (by Author) - 1234 (1234-4567), descriptions (best), more descriptions';

console.log(text.replace(/^\([^)]*\)[^/]*?\/\s*([^(]*?)\s*\([^)]*\)\s*-\s*(\d+)\s*\([^)]*\),\s*(.*?)\s\(.*$/gm, '$1 ($2) ($3)'));

Thank you so much, but it works for specific case. I'm trying to make it works for some cases — Hung PD, Jul 16 '21 at 13:58
