Is it better to have one return statement per function?
This method makes code maintenance extremely difficult and error prone. Structured programming says you should only ever have one return statement per function. This is to limit the complexity. Many people such as Martin Fowler argue that it is simpler to write functions with multiple return statements.
What’s the best way to return an IF statement?
