> Learn how methods work in Go, functions attached to a struct, and the difference between a value receiver that copies and a pointer receiver.

A function can be assigned to a struct and in this case we call it *method*.

Example:

```go
type Person struct {
	Name string
	Age int
}

func (p Person) Speak() {
	fmt.Println("Hello from " + p.Name)
}

func main() {
	flavio := Person{Age: 39, Name: "Flavio"}
	flavio.Speak()
}
```

Methods can be declared to be pointer receiver or value receiver.

The above example shows a value receiver, it receives a copy of the struct instance.

This would be a pointer receiver that receives the pointer to the struct instance:

```go
func (p *Person) Speak() {
	fmt.Println("Hello from " + p.Name)
}
```
