In the previous episode, you were introduced to the set. You saw that sets have no order and remove duplicates. But I didn’t go into the real power behind behind sets. And that’s comparing sets to other other sets.

var electricCars = { 'Tesla', 'Ford', 'BMW', 'Rivian' };
var gasCars = { 'Ford', 'Ram', 'BMW'};
var allCars = gasCars.union(electricCars);
print(allCars);
var justGasCars = gasCars.difference(electricCars);
print(justGasCars);

print(makesGasAndElectricCars);
