Perhaps there is something about the nature of the addEventListener() method that I do not understand, but how/why does the argument named 'event' actually target the event object? I know it is named 'event' strictly for naming conventions, and that if we named it something else, it would have the same behavior. Does the callback function take an event object by default as an argument?

Full Stack JavaScript Techdegree Graduate 17,506 PointsThank you for the response. It looks like the event object is passed as the argument by default.
