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.

It is still possible to pass with one-liner using strings and regex. The shortcut checking test just makes it a tiny bit more complicated.
you are getting it wrong . Kata dose not want you to know the shotcut but dont want you to use it.
your code probably use strings to check for '[]' in original and other but one of the array is something like this [1,'[',']'],['[',']',1].
