i found this kinda funny, the title literally say "Lost Without a Map", but here you are using a "Map()" xDD
its still a good solution tho

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

i think so 👀

This is so smart. Thank you for sharing that. Also good point on the effects of sorting for larger arrays

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.

If the execution in your if statement is a return, you don't need an else block after it, because the function will not continue to execute once it's returned.

And with the spread operator, you can now simplify the use of Math.min and Math.max to Math.min(...array) and Math.max(...array), respectively.

If your parameter is undefined will your code work?
I mean when arguments like Nothing, None are passed into the function will it work?

You don't need to reassign the array variable like this 'array = array.sort', because sort() is already mutating the array, also be afraid that it will mutate the initial array from the argument, hence better to do something like this 'const innerArray = [...array] and work with it.

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