Thanks for the explanation, I think I confused my "case sensitive" with "case insensitive".

Hey RichardB, thanks so much for sharing that link to currying. It was a really good read...

So the instructions say that the rating is case "insensitive" - but I'm pretty sure you have to change the rating to lowercase to have pass the tests.

Wow - I still don't get this one. I read up on the conditional (ternary) operator but still don't understand why you need have bark === undefined? Any pointers/links would be greatly appreciated. I feel like I'm missing something big here...

Thanks for your suggestion @jrmoser - I managed to read up and solve the Kata thanks to you.

Yup - I'm getting the same error but passing all other tests (yet it works in my Chrome console). Can someone please link to a page so we can read up on this more? I've read the ES6 Generator MDN pages and I'm still stuck. Cheers...

simple...thank you!
