func main() {
  src := []Person{{Name: "suparman"}}
  target := []Person{}
  newTarget := []int{1, 2, 3, 4, 5}

  compare := InstanceOf(src, target)
  compare2 := reflect.DeepEqual(src, target)
  compare3 := reflect.TypeOf(src).Kind().String() == reflect.TypeOf(target).Kind().String()
  compare4 := reflect.ValueOf(src).Kind().String() == reflect.ValueOf(target).Kind().String()
  compare5 := InstanceOf(src, newTarget)

  fmt.Println(compare)  // true
  fmt.Println(compare2) // false
  fmt.Println(compare3) // true -> this is true because this is comparing type data slice with slice equal true
  fmt.Println(compare4) // true -> this is true because this is comparing type data slice with slice equal true
  fmt.Println(compare5) // false -> this is false because type data is match but reference address data is not match and then equal false
