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.
Thanks Ambrelium, finally understood.
string.match() will return null if there's no match, and null has no property named 'length". So by doing || [], you ensure that length will work

I can see them too.
Maybe something in the parsing mechanics went wrong.
Vote this up! Concise solution!
I wonder how the length of an empty array could be 26?
Like, why not return (string.match(/([a-z])(?!.*\1)/ig)).length === 26;?
//And why doesn't the editor consider my RegExp to end...?
(I'm not very good at RegExp's, forgive me)
