   1:  function logArguments(...args) { // Using rest parameters. args will be array

   2:      console.log(args); // Now args is true array, because rest operator is used

   3:  }

   5:  logArguments(1, 'apple', true, {});

6:

   7:  function passArguments(fn, ...args) { // Rest operator

   8:      fn(...args); // Spread operator

   9:  }

  11:  passArguments(logArguments, 5, 'orange', false);

[ 1, 'apple', true, {} ]
[ 5, 'orange', false ]
