yes, the solution typically requires a somewhat large amount of code compared to other katas. my reference JS solution is around 100 lines long. i think you are writing too much code because your logic is to start from the pieces and stop at the king, but the other way around is easier (requires less code).

I need help guys. As I understood, my logical is that firstly:

1. I need describe each figure(how it is beat king)
2. I need find figure and king?
3. I need check is King in Check?
   Is that some trick in this kata?
   How much code am I need to write to solve this kata?
   Because I did logical for pown and have already 86 string of code(it works ok), but is it ok?
   Guess If i end this kata I will have maybe 300-500 string of code. Just answer, is my logical which I described upper, correct ?

() has special meaning in what you're using.

Ok, I saw my error. Sorry)))Thanks for help

try this one: "abc(def)B4B(jkl)mno"

console.log(s)?

Your regular expression is wrong, you can test it here: https://regex101.com/ make sure you select ECMAScript in flavor at the left.

Hi eeNNdd11, I agree that description can be better but still this is not a reason to be rude. If you finished the kata you will see "How satisfied are you with this kata?" - you can choose. My personal vote is 'somewhat'. Chrono79 just pointed you to some already posted answers and it is little bit strange that you argue with him about next g964 kata.
