Now to dive into the last challenge for this course. This challenge is going to read like a math problem, so buckle up and hold on. Raunaq, Jean, Eric, Yogesh and Sally took a plane trip to Osaka. Raunaq and Eric had the vegetarian dinner. They rest had the fish dinner. Unfortunately, the fish was bad and made everyone sick. Using a set, print out the people who at the fish. Pause the video now and try it out.

var passengers = { 'Raunaq', 'Jean', 'Eric', 'Yogesh', 'Sally'};
var veggie = { 'Raunaq', 'Eric' };
var sickPassengers = passengers.difference(veggie);
for (var passenger in sickPassengers) {
    print(passenger);
}
