@juanignaciomalerb4 Incorrect. If the array is empty, then 0 / 0 is done, which results in NaN (which is the expected result).

ooooh it makes sense now

I think because in the sum prototype he gives an initial value of 0 in the reduce function. So if an empty array is passed that will be the default value

Did you just go ballistic over a year old comment on not yours solution? :thinking:

Why you on every post just hating like your own solution is way more complicated than the toString which is simpler and that makes your solution an overengineered piece of shit. How does it feel to take some of your own medicine asshole, huh?

Not even any constructive criticism you think you're such a smartass yet can't even speak without hating. Stupid loser

what about empty array? does average() method still work?

you could improve code by removing sum += i line because you can do sum with count * (count + 1) / 2 formula. Also, you can move sum and str declarations after count < 0 and count === 0 if blocks because if count <= 0 true, you aren't using these variables but doing extra step declaring them. Also, you can give str initial value "0" so you can start loop with i = 1; no extra looping required :)

you could use for ... of loop because you are not using i index . it would the code more

lol

good point

bloody beautiful!

you don't have to check every time n !== 0 case. if before everything else,if you check !n case and return, you would reduce execution time and redundancy.Also it's not good practice to mutate input.

mutating array isn't
