// ==== Challenge 1: Use .forEach() ====

// ==== Challenge 3: Use .filter() ====
// The large shirts won't be available for the event due to an ordering issue. Get a list of runners with large sized shirts so they can choose a different size. Return an array named largeShirts that contains information about the runners that have a shirt size of L and log the result
