How could you append/prepend to an existing variable to a parameter passed in a function? In English: I have a strict naming structure for multiple properties. E.g. bananaFill, kiwiFill, bananaRadius, kiwiRadius. How can I act on both the `Fill` and `Radius` properties by just writing one `fruit` parameter in the function? See the attached images for the clearest representation of what I'm trying to do. Thanks!
