Is it a misuse of reduce to modify acc (because, ideally in functional programming, things are immutable), or does returning acc from the reducer function mitigate that?
Hey! Thanks!
I would go for the mitigation :P
const groupCitiesByRotatedNames = cities => newArray
I guess you could return always a clone of acc? For the purpose of the article, I would not give too much importance to this to be honest :)
