Challenge 02 - Satisfying Interfaces in Go

In this challenge, you are going to implement the necessary methods needed to satisfy the provided Go interface.

On the left hand screen, you have a simple Go application that features an interface called Employee.

In order to complete this challenge, you will have to complete the code and satisfy this interface.

package main

type Employee interface {
    Language() string
    Age() int
}

type Engineer struct {
    Name string
}

func (e Engineer) Age() int {
  return 26
}

func (e Engineer) Language() string {
    return e.Name + " programs in Go"
}

func main() {
    // This will throw an error
    var programmers []Employee
    elliot := Engineer{Name: "Elliot"}
    // Engineer does not implement the Employee interface
    // you'll need to implement Age() and Random()
    programmers = append(programmers, elliot)
}
