Is there an efficiency difference between using and in an if statement and using multiple if statements? In other words, is something like

Answer 1

This isn't enough of a performance difference, if any, to affect your decision. IMO, the decision here should be made purely from a readability perspective. The first is generally more standard, I think, but there are situations when the second might be clearer. Choose the method that best gets your intent across.
