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.
^ CORRECTIONS AND TO BE MORE SPECIFIC:
The + means to match whatever is infront of it 1 or more times**
Then you have the astric * (which is not included but important to differentiate from the plus) it matches whatever is infront of it from 0 or more times.
And finally g the global tells regex to not stop after the first match but continue and look for more matches
