You’ll also learn about Pair and Triple, which allow you to make your own types made up of two or three values of any type, respectively.įinally, you’ll learn about the important types Any, Unit, and Nothing. You’ll learn about converting between types and you’ll also be introduced to type inference which makes your life as a programmer a lot simpler. In this chapter, you’ll learn about handling different types, including strings which allow you to represent text. Formally, a type describes a set of values and the operations that can be performed on them. Now that you know how to perform basic operations and manipulate data using operations, it’s time to learn more about types.
