Go Fundamentals: Gopher Guides

3. Arrays, Slices, and Iteration

In this chapter, we cover the built-in list types: arrays and slices. Next, we move on to discussing Go’s for keyword for iteration. Finally, we cover using the range keyword to simplify iteration.

List Types: Arrays and Slices

Go has two built-in ordered list collection types: arrays and slices. Unlike other languages, there are no built-in complex list types such as linked lists¹ or trees.² Instead, Go uses the concept of composition³ to allow for creating more complex data structures, an example of which can be found with the list.List⁴ type. We cover composition in more detail as we progress through this book.
