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.
This is a really nice kata!
I really felt like this was sort of a gross mess to write....but pivot tables are usually a gross mess to create in most cases, so good job on actually hitting this one right on! :D
If I remember correctly, it started as poor practice because, while various systems processed it fine, it potentially led to some tricky reference situations. As far as I'm aware this is pretty well mitigated now by smarter backend processing in pretty much every system, particularly Postgres, so it is sort of a moot thing. Could also just be me being nitpicky because that's how I learned?
