Question

Are there good reasons why it’s a better practice to have only one return statement in a function?

Or is it okay to return from a function as soon as it is logically correct to do so, meaning there may be many return statements in the function?

Answer 1

I often have several statements at the start of a method to return for ‘easy’ situations. For example, this:

public void DoStuff(Foo foo) {     if (foo != null)     {         ...     } } 

… can be made more readable (IMHO) like this:

public void DoStuff(Foo foo) {     if (foo == null) return;      ... } 

So yes, I think it’s fine to have multiple ‘exit points’ from a function/method.
