I have the same issues i think, have you managed to pass the tests since then?

I liked it, looks cool for small arrays

Im trying to do it with js, my code works fine and passes all the test but it gives me back a type error like this: TypeError: Cannot read property 'toLowerCase' of undefined at getCount. If I change it to not use the toLowerCase function, it gives the same error with the .length property somewhere else.
I have no idea what's going on, scope issue? broken kata? Hope someone can shed some light on me
