Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
KANYE WEST!
Love it. Way more succinct than mine.
That's a great solution
took me 10 seconds to understand it
dirs is an accumulator which has been initialized as []
Sorry, first time commenting, already marked as spoiler. You could review my code, mine have never been reviewed. Thank you.
Sorry for my bad English. Google translate

Can someone tell me what the values of "dirs" and "dir" is on the first iteration? I also don't know what the value of dirs[dirs.length - 1] is can someone tell me what that would be? I don't use the array methods that often, but I know that if the initial value is not given then it usually starts with the first two values in the array, like arr[0] and arr[1].
Really not bad and usual code for understanding. I often forget the reduce can be used for array and etc not only for numbers
that's taken me a little bit of time to finger out why coding like this, why stack. nice work!
That's efficient and really clever. I didn't think of popping the array
Man im struggling to remember that reduce can also be used to initialize arrays. Nice one!
