I published a fork with the new description, please check and approve both solutions
Thanks for try, I'm going to unpublish the translation and try to remake it.
Sorry for the inconvenience

Thanks, check out Array.prototype.reduce() as well, if you don't know it already. It's a bit harder than other array methods like map and forEach but its very powerful :)
Thank you, I just try to live up to my (bad) reputation as king of the one-liners ;)
I just submitted 3 translations for this kata and a bit of feed, let me know if I might be of further help.
