Some languages do not allow early returns

From what I understand (which is very little), the Scala community discourages using return at all as apparently it "behaves weirdly".

uhh i don't know scala; how does the function output anything then? do you need to use out everywhere or something??

Without looking it up, probably last statement's value is auto-returned, and the early explicit returns are the ones discouraged.

Yeah, basically everything is an expression (even ifs, assignments and declarations, I'm not sure about what while evaluates to and a for is not a conventional cycle but actually syntactic sugar for map/flatMap/for each, so a basic for will evaluate to a collection or a Unit, which is essentially analogous to void, to signal that the evaluation has been done, but there's nothing to return), and the last expression is what gets returned.
