A function doesn't need to return something to be useful. It could test the state of something and make a sound if a certain state is detected. It could change the screen colour or make a notification light flash. It could prompt for user input and set a variable depending on what input is collected. There are many things that a function can do that doesn't require a value to be returned from it.
I hope that helps,
Steve.
