No tiene sentido el tuyo por que .map() internamente crea una nueva matriz con los values

These solutions showing me how I need to think differently and not overcomplicate things lol.

it may be a bit redundant to make the Human class abstract here, since there are no methods or attributes inherrited by man or woman, so theres no common behavior to impliment

i think so 👀

same here. One day...

it is returning a new array, you don't need to name it

But the system is saying that it should be another array, not the initial one.
Very strange.

you are clever!

but this doesn't create a new Array, only replaces existing one?

Awesome, that is what I thought. Thank you!

In this code, is the + 1 accounting for the col that we are in?

Best!
