A brief example of how we can achieve composition in go. Composition is not anything like inheritance it's just embed one struct to another to maintain data inheritance in it's own way.

composition.go

// Person struct
type Person struct {
	FirstName       string
	LastName        string
	Age             int
	TotalExperience int
}

// Person struct embedded in Job struct
type Job struct {
	Skill    string
	Hobbies  string
	JobTitle string
	Person
}

func (p Person) getName() string {
	return p.FirstName + " " + p.LastName
}

func (j Job) candidateEligibility() string {
	if j.JobTitle == "Software Engineer" && j.Skill == "Golang" && j.TotalExperience == 3 {
		return "You're eligible for this job."
	}
	return "Sorry, you're not eligible. Best of luck!"
}

func main() {
	personData := Person{
		FirstName:       "Nikhil",
		LastName:        "Vaidyar",
		Age:             25,
		TotalExperience: 3,
	}
	jobData := Job{
		Skill:    "Golang",
		Hobbies:  "Travelling",
		JobTitle: "Software Engineer",
		Person:   personData,
	}
	fmt.Println(jobData.getName())
	fmt.Println(jobData.candidateEligibility())
}
