Control Flow via Return vs. If/Else [closed]

Answer 1

First option, using return, is better, because:

1. you have a place to put all guards and preconditions, near your asserts and all that stuff.
2. for me, it's easier to think "let's see all that can be wrong, and return. From this point, I have everything I need and I am on the Happy Path
3. if you do use the if / else approach, you have all code in that method / function indented. Add other if, or for, and things start to get funny

One proponent of this method (return) is Marcus Zarra, in the Cocoa is my Girlfriend coding style
