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.
Thanks, I've actually worked quite a lot with JavaScript, but for web and api development so I never came across this "misuse".
Will give other code golf katas a try and then come back to this.
I'm new to this, I've been trying it for a while and have no idea (I didn't even know I could use _ as a variable).
I don't wanna look at the solutions, anything that could lead me to solve it?
