Yeah. The example is not very good, as it would probably be better to write as switch expression. But on a complex function, returning early can avoid the need

Yeah. The example is not very good, as it would probably be better to write as switch expression. But on a complex function, returning early can avoid the need to retain a lot of context in your head while reading that code. I find it especially helpful for returning/throwing on error conditions or breaking out of recursion.
