You just taught me how to use reduce, thank you!

as newbie i could have an aproach. I think the key to understand this, is know that Math.sign() return an integer ; -1 (negative), 0(zero), 1(positive). Then uses this to calculate the proper index of the list [3,4,2,1][index] where index = (0,5 if x is pos OR -0,5 if x is neg) + (0,5 if Y is neg OR 2,5 if Y is pos) it always result into an integer form 0 to 3 that selects the value in the arbitrary order is set.

too much maths

can you explain

took me a minute to understand but i overall like the way you did this problem

great code and cool name! id say make the code look a little prettier though so its more readable

i like this code

i realize now that i couldve swapped the if statements to use less code lol
