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.

I had the same difficulty/confusion. The examples indicate that we are to return the number of divisors followed by an array containing each divisor, but the correct answer only included the number of divisors.
I agree. The implication is a single X or Y, but the tests are expecting XX or XY.
It's just a JS (and many other languages) strings feature. You can also slice them.
Does this work because inputString is treated as an array when followed by square brackets?
