// immagina che pippo e giggio siano due oggetti molto più complessi 
// e che tu conosca la signature con la quale verrà lanciata la funzione callback di 
// highGreetings. Non hai bisogno del primo parametro, ma solo del secondo.
const highGreetings = (fn) => 
  fn('pippo', 'gigio')
    
// hai bisogno per forza di gigio
// una possibilità è:
highGreetings((_, y) => {
