Type embedding

But what if you would like a struct to inherit the methods of another struct? The closest feature that the Go language offers to the concept of inheritance is known as type embedding. This feature is best explained through an example. Let's go back to the Person struct type:

type Person struct{    name string    age int}func (p Person) GetName()string{  return p.name}func (p Person) GetAge()int{  return p.age}
