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.
same here with Ruby, when I do print array 1 or array2 I can see that the 4th line array is empty.
According to the kata conditions ([] or nil) the result should then be false.
I can't see why it is expecting true.
