Chapter 8. Methods, Interfaces, and Objects
Using your skills at this point, you can write an effective Go program using the fundamental concepts covered so far. As you will see in this chapter, the Go type system can support idioms that go beyond simple functions.

Go methods
Objects in Go
The interface type
Type assertion
