I agree with you: the top-to-bottom narrative works better. Declaring such functions before they are used makes you wonder what’s happening, before you see the usage, when you read the code.

And I think the way the code is set now is good. My brain is not bothered by the function being declared after it’s used, even if it’s inside the current scope, because it’s a function declaration.

P.S. no worries about not having run the examples. You’re right, they’re illustrations. I was just curious about that particular case as I found it surprising (then again, programming languages are full of surprises) and I’m not a JS expert.
