What are some advanced examples of Go methods?

Can you provide some advanced examples of methods in Go?

Sure! In Go, methods are functions with a special receiver argument. For example, you can define a method on a struct.

Can you show me a specific example with a struct?

Absolutely! Here's a struct called 'Circle' with a method to calculate its area:

type Circle struct {
    Radius float64
}

func (c Circle) Area() float64 {
    return math.Pi * c.Radius * c.Radius
}

You can call circle.Area() to get the area.

What about using pointers with methods?

Great question! Using pointers allows you to modify the receiver. Here's an example:

func (c *Circle) Scale(factor float64) {
    c.Radius *= factor
}

This method scales the radius of the circle.

Can methods be defined on interfaces too?

Yes, methods can be defined on interfaces! For instance, you can define an interface 'Shape' with a method 'Area' that different shapes implement.
