The three types we learned about in this chapter were String, Int, and Double. In the subsequent chapters, we will introduce you to many more types.

Now that we have an understanding as to what a type is, in the next chapter, we will introduce you to functions. Functions can be summed up as actions that can be performed in your code. A car can turn right or left and these can be considered actions (or functions) that you perform on a car. Functions are self-contained chunks of code that you can think of as actions. We will cover what functions are and how to call them in the next chapter.
