Yep, fixed!

I see what you mean: the fixed/sample tests go from gibberish to real sentences instead of the other way around. I reversed the order, can you check if it is OK for you now ?

what do you mean by input and output ? I ran the initial code, and the order of expected and actual seemed correct to me

Looks like input and output are reversed in Lua. While this doesn't change the solution, it did puzzle me for a moment because it doesn't match the description.

Thanks for the compassion, lol.

Nice. A bit cleaner than mine, I'll admit.

You're correct, it's best to use let in nearly all cases, unless you know what you're doing. I suspect that many of these solutions are old, posted either before let was introduced, or prior to its widespread usage.

description updated

great, fixed

I was thinking the same thing. An example would help quite a bit.

There can be no room for debate that this is best practice
