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.

Hi I am struggling a bit on the tests. One error says that I am modifying the input array. But the first thing I do is
copy it with new Array() and Array.from(). Secondly in Glider 4 it demands an untrimmed array but the instructions say to trim
around the live cells.
