What he is saying is that the function is mutating the original signature array.
You should make a copy of the signature array. You can do that with const aryintSignature_Copy = [...signature];

Wow, such a clever sollution!
I was breaking my head on excluding those 'edge cases' (n =< signature.length) from the loop.

What would be a good practice to eliminate overcomplification?
Is it to write all possible inputs and outputs in 1 overview to spot the most efficient pattern?

But thnx, this was a great lesson.

Based solution

Best solution with the nicest reference. Love it. <3
