thanks for including formula name I collect these lol

what a troll lol, you're just mad you had to use a loop like a LOSER. good for you though commenting an explanation of what an odd number is, really top notch best practice stuff. Do you usually go on codewars before or after your shift at google?

i hated it, good kata

born too late to explore the earth, too early to explore the stars, but just in time to spend 3 hours on a 30 minute kata that I'll forget by the time I walk into my graveyard shift at the gas station tonight. all in a day's work baby

Good job on the testing, very thorough. Really forces you to organize and be orderly. I'll be referencing this when I try to make my own kata. ++

i need to stop following rules...

nice exploit doc.

!! is used to convert a truthy/falsy value to its boolean equivalent.

let num = 5; (truthy)
!num // false
!!num // true

let num = 0; (falsy)
!num // true
!!num // false

comparing 5 with !!5 would be the equivalent of comparing 5 with true (which is false)
5 === !!5
5 === true

The only reason people still use it over Boolean (other than wanting to look like elite hackers) is because it's something like 10-15% faster (last time I checked)

oh thats spicy

yeah, you're right, this bugged me for a while too, but I finally figured this out after a little online searching and the satisfaction of passing all the tests was soooo good.

it does have a puzzle tag at least

I believe the "Unspecified AssertionError" that many are getting is most likely related to an improper use of "this" when it comes to chaining methods
