I don't know how much I am enjoying finish this challenge.
Seems something "alien" the first as you saw it, but it's pretty simple tho.

I recommend you start your research from spread operators.

Really enjoyed this kata. Idk how I never thought about that

For those who don't know where to start, look up on what thing JS OO is based

Great kata.

JavaScript. There's no function, no valid variable given(you cant use Number as it is a key word, only enough explanation to leave one utterly confused. Just a waste of time. At least give it a puzzle tag. Am I supposed to return something? Tried a number of things, nothing works.

For those who do not know where to start, I suggest searching up MDN's spread syntax page as a jumping point for your research. I'm certain that everyone is smart enough to figure things out from there.

It took me some time too. Check out the easier kata first, linked in the description. Solving that one first aided me in solving this one.

No, sounds like the right direction.

Where a and b are positive or negative integers.

There are tests with zeros.

This is one of those that if you know you know. I dont think logic works here that much.

I've been trying to wrap my head around it

this looks suspicious o_O

huh? 0_0

Something with zeroes, also, perhaps?
