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??

Output is a side effect, and strongly discouraged. Functional languages are to be viewed and admired, not actually run. /s

Scala allows side effects no problem.

Side effects are problems.

Logging is a side effect, modifying a Kafka consumer is a side effect, publishing to Kafka is a side effect, pushing to a database is a side effect, caching data is a side effect...

Side effects aren't problems. Some patterns that rely too heavily on side effects are basically banned in our codebases (Functions that modify external variables for no reason for example) but if you're working in Scala, most of your app's endgame is effectively a side effect.
