1,107 PointsWeird output
var airport: [String: String] = ["YVR": "Vancouver Airport", "JFK": "JFK International Airport"]
print(airport["JFK"])
When I enter the above code the output is:
Optional("JFK International Airport")
Why is it printing optional? I am using a web compiler because my mac isn't with me until next week.
