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.
Specs promise string arguments. Testing is done on
nulls as well, and it's unspecified what value should be returned for that.If you want to somehow cater for callers not passing [ enough ] arguments, you should be testing with
undefined, notnull( so default arguments would work. onnull, they don't ).The kata is apparently published.
