Constructors in Golang

There are no default constructors in Go, but you can declare methods for any type. You could make it a habit to declare a method called "Init". Not sure if how this relates to best practices, but it helps keep names short without loosing clarity.
package main

import "fmt"

type Employee struct {
    Name string
    Age int
}

func (e *Employee) Init(name string, age int) {
    e.Name = name
    e.Age = age
}

func info(name string, age int) *Employee {
    e := new(Employee)
    e.Name = name
    e.Age = age   
    return e
}

func main() {
    emp := new(Employee)
    emp.Init("John Doe",25)
    fmt.Printf("%s: %d\n", emp.Name, emp.Age)
	
	empInfo := info("John Doe",25)
	fmt.Printf("%v",empInfo)
}
C:\golang\codes>go run example23.go
John Doe: 25
