so funny, first test in kata incorrectly set, try immediately attempt (JS)

This does not sound right. Can you show your code, and an example input which you think is handled incorrectly?

random checks produce different results, sometimes ")" is ")", and sometimes "(", although they are not repeated.

It is a pity that the condition does not say that arrays can be of different sizes and they may not exist at all

the problem with the kata is that they do not say that you can take away from zero , and so the easiest
