Solution for your first kata can be shortened as

const solution = num =>
  num.reduce((acc, elm) => acc + ((elm % 3 === 0 || elm % 5 === 0) && elm),  0)

Thanks, it did improve the time complexity too

[Oğuzhan Olguncu]

Shortened it even more. Cheers.

I just tried to submit it but it didn't work

[Oğuzhan Olguncu]

I have not checked the kata, but my solution assumes given parameter is Array. That might be the source of your problem.

[Youssef Rabei]

I guessed that and it's one of the problems and i fixed it by transform the given number to an array of digits and then run your code over it but it returned 0
