// plain vanilla js
  // inventors.push.apply(inventors, newInventors)
  inventors.push(...newInventors)
  console.log(inventors);
  
// es6 version - using spread
  const inventors = ['Einstein', 'Newton', 'Galileo'];
  const newInventors = ['Musk', 'Jobs'];



const name = ['Joe', 'Boo'];
function sayHi(first, last) {
  alert(`Hey there ${first} ${last}`);
