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.

Thanks for the suggestion. I was just starting when I wrote this solution. I realized i could optomize this.
Damn, thats the most funky way to solve this, would have never thought of this.
the solution could be written on a single line, but lets say that you can write it like this so its more readable, it is best to use "const" instead of "let".
Happy coding :D
