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.

correct me if I'm wrong, but shouldn't there be a word "without" instead of "with" in the description?
Many thanks! Was super tired and missed that one :)
Can't pass this test:
[] should equal ''
so if (text) is empty, what exactly shoud be returned?
Thank you!

I mean, it was not obvious to me while reading the task's description. Maybe it's just because of my poor English skills.
Not very obvious if distinct letters should come from both s1 and s2 before they are merged or after.
I see! Thank you!
