Now it's time to discover the power feature of using a method. This usually means sending data to the method, which you just learned to do. Then we have the method return a value. Previously, we used a void
type method. I have mentioned before that this is a keyword for nothing, which means that the function isn't returning anything.
Let's learn about return
type functions now. We won't use void
anymore. Instead of that, we will write the type of data that we want our method to return. Don't worry if this sounds complicated; it isn't. I remember that, years ago, I had some issues getting my head around it. In practice, this is a very simple concept.
