const starWars = ["Luke", "Finn", "Rey", "Kylo", "Droids"]
const thrones = ["Jon", "Danny", "Tyrion", "The Mountain", "Cersei"]
console.log(droids(starWars)) // should log: "Found Droids!"

//A simpler approach 

console.log(starWars.includes('Droids') ? 'Droid Found' : 'These are not the droids you\'re looking for');
console.log(thrones.includes('Droids') ? 'Droid Found' : 'These are not the droids you\'re looking for');
