Create datatypes that use lists

- [Voiceover] At this point, we've seen how to create our own datatypes of lists, for example, primes. We've also seen how to perform functions on lists. This time I want to show you how you can create a datatype that contains both primitive data and a list. In this example, we're going to model the process of making a salad. When making a salad you first choose what type of lettuce you want. Next, you put on a dressing and then you might have one or more toppings. So we will have lettuce, dressing, and a list of toppings. Let's get started. First, I'm going to create a datatype called lettuce. And the possible values for lettuce are going to be Romaine, IceBerg, SpringMix, and Spinach. Next, I need a datatype to represent the dressing for the salad. The dressings might be Italian, Caesar, Ranch, French, or BleuCheese. Now I need a datatype for my toppings. The toppings might include, Olives, Tomatoes, Parmesan, Cucumbers, Onions, and for now let's just add Croutons. There's lot more…
