Ah, cheers! I'm not sure it's the most efficient one, but I think it's neat :p

Glad you liked it :)

Hey, thanks :)
I've been using !!a lot recently - it's just a nice short alternative to writing out === true

No problem, so if you have questions (and i'm able to give an answer)... ;-)

Thanks to your tutorial :).

Hi again;-), there are different ways to floor a number, this is one way (for example "~~" another). It's not the same as Math.floor, but here it works. It's a "bitwise or" which cuts the part behind the "." and so it gets the integer part of these small and positive numbers here...

Thanks for your advice. I will use Infinity from now. :)

Yes... it's not always necessary to use an object/dictionary;-)... Surely normally it's not efficient (indexOf works in O(n)), but short and simple for this really simple kata:-)...

Well, I hope at least that is the case with all the people I forced to do this kata :D

Thanks for your feed, cheers!

Glad I taught even a single person something new and good, then :)
