My solution to this was about as attractive as a massacre :D, found this tougher than some of the 4kyus I have done :)

Elegant man!

I Should have just messed with the traits and mutability, nice though!

Really nice kata, nearly solved it a different way but couldnt get past overflows and timeouts. Gave me chance to dive into some math i was not entirely familiar with.

Thanks!

The version of Node.js required for this solution was added less than 5 months ago, so the solution has had much less time to collect votes compared to the current top 6-year-old solution.

this is the same answer i provided, but it seems like it's not the most popular one. the more popular ones are much more verbose, and i dont understand them. can anyone explain if there are any disadvantages to using this method?

Wow that was tough, 4 months into development and that one caned my ass. Took me a good 6 hours to pass all tests. Im such a bloody noob :D
