Inheritance

There is no inheritance in Go, but you can embed types. Here is an example of a Person and Doctor types, which embeds the Person type. Instead of inheriting the behavior of Person directly, it stores the Person object as a variable, which brings with it all of its expected Person methods and attributes:

package main

import (
   "fmt"
   "reflect"
)

type Person struct {
   Name string
   Age  int
} 

type Doctor struct {
   Person         Person
   Specialization string
}

func main() {
   nanodano := Person{
      Name: "NanoDano",
      Age:  99,
   } 

   drDano := Doctor{
      Person:         nanodano,
      Specialization: "Hacking",
   }

   fmt.Println(reflect.TypeOf(nanodano))
   fmt.Println(nanodano)

   fmt.Println(reflect.TypeOf(drDano))
   fmt.Println(drDano)
}
