)

func main() {
  emitter := emission.NewEmitter()

  hello := func(to string) {
    fmt.Printf("Hello %s!\n", to)
  }
  
  count := func(count int) {
    for i := 0; i < count; i++ {
      fmt.Println(i)
    }
  }
  
  emitter.On("hello", hello).
    On("count", count).
    Emit("hello", "world").
    Emit("count", 5)
}
