In this lesson, you learned about lists. You learned why lists are more flexible than arrays. You summarized values in a list, learned about generic namespaces, started a list of doubles, and filled the list. You also displayed the max, min, average, and sum operators, then squared the results, and finally, you explored nested lists.
In the next chapter, you are going to learn about polymorphism. You will focus on two types of polymorphism, or objects, being treated as different forms depending on the context. The practical benefit of this is that you will write less code.
