P 49 – fixed
P 54 – that’s a formatting error, I think – _start_ should be indicating underlines.
P 55 – switched
P 55 – It’s not superfluous, it’s there as part of what I guess I’d call an idiom, and gives the sentence a different rhythm
P 58-59 – The apostrophe is in the regex because it was needed for the 2010 example (which I’ve changed). But I don’t think it’s hurting anything to keep it there?
P 62 – Yeah, I noticed that right after the beta went out. It’s been fixed – the code example was changed a couple of times to bring it to 2023 standards (so, no for loop…) and the text lagged behind the code in this case.
P 63 – I think what “this” is referring to is ambiguous, I’ll clarify. reverse_each is part of aligning the code with Standard Ruby style rules, so I’d prefer not to change it.
P 64 – Yes that would probably be clearer.
Thanks!
