JavaScript

Kata needs some random cases. I have written a weird logic and it is able to clear all test cases. However, when I assert my own random test, the code fails. Coincidence, probably. But thats why I think it needs some random cases.

Can anyone explain to me why the second loop annihilates the input board arrays, even though i am giving square a copy of it using board.splice()?

I was confused on this as I am also used to applying list functions on strings so assumed nesting could be done in both arrays and strings. Thank you for this clarification :3

Also another question is does [[]] has the same nesting structure as [""] or no? if yes can u further nest in strings or is this only possible with lists?

My solution is not very elegant but it works good enough. Very fun kata regardless
