Golang nested struct

Very interesting, for Golang nested struct, we can directly visit the lower level struct’s field.

An example can be found in the go playground

The code is here

package main
import "fmt"
// This `person` struct type has `name` and `age` fields.
type person struct {
 name string
 age  int
}
type personNew struct {
 person
 address string
}
func main() {
 fmt.Println(person{"Bob", 20})
 personNew := personNew{person{"Jimmy", 40}, "staten island"}
 fmt.Println(personNew)
 fmt.Println(personNew.person.age)
 // output here is same as above
 fmt.Println(personNew.age)
}

Output

{Bob 20}
{{Jimmy 40} staten island}
40
40
