I’m not sure this is a good example of case class. We generally use case objects when there are no fields. To me, the purpose of case classes is to aggregate information (in their fields).

I wanted to keep the concept of case classes simple before moving on to pattern matching. I know there are a few features that I didn't discuss like toString, hashcode, etc. I didn't think they were worth mentioning but feel free to disagree.
