It can definitively happen, but I think more times than not the others are more readable.

To be honest this seems to be a familiarity thing > but with reduce you need to know what arguments in a callback mean

If I didn't know for it would be mind boggling what those 3 things, separated by semicolons, are doing It doesn't look like anything in the usual language(s) they're implemented. It's the same with switch.

The only thing both of them have, for and switch, and helps, is that languages that offer it and aren't FP usually use the same *C* form across all, whereas reduce's args and the callback args vary a bit more between languages, and specially between mutable and immutable langs.

I still prefer most of the time the functional specific counterparts.
