// IsBigger is a plain function that compares two integers
// and return true if the first is bigger than the second ;-)
func IsBigger(first, second int) bool {
   return first > second
}

// Compare is a higher order function that compares two integers via a function
// that is passed in as the third parameter using explicit annotation,
// so the full function signature is annotating the type of the parameter
func Compare(first, second int, compareFn func(first, second int) bool) bool {
   return compareFn(first, second)
}
