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.
Despite what many people say about regular expressions this looks very accurate!
The rule is simple: Do not expand the scope if no one asks about it.
wow
What about unicode chars? The Kata only supports PHP 7.0, so some string functions would have to be backported manually. :(
interesting
