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.
I really like this idea of filtering out the negative items first!
That's how I did it :D

Impressive)
practice more
goood job
Neat! Very clean.
Unrelated: reading your solution made Big O notation make sense to me. :)
Every item in the incoming array is processed twice, first to remove everything that's equal to or greater than zero to a fresh array, and then to sum every element of that new list. Every item is essentially touched twice so it's O squared, but technically maybe it's kind of smaller than that in an ideal case because the reducer only does its work on the resulting, probably smaller, subset of filtered numbers.
Thanks, I know this is sort of unrelated, I just needed to go off for a sec.

I am not splitting hairs, but isn't it regarded as bad practice to omit curly brackets around statements? I vaguely remember having read about it somewhere at MDN though.
