+               //              any other, triggering the second whenever the first is called. Many
+               //              listeners may be attached to a function, and source functions may

+               //              "regular" JavaScript function or a DOM event, it provides a uniform
+               //              interface for listening to all the types of events that an
+               //              application is likely to deal with though a single, unified
+               //              interface. DOM programmers may want to think of it as
+               //              "addEventListener for everything and anything".
+               //
+               //              When setting up a connection, the `event` parameter must be a

+               //              not fail, but will instead set up a stub method. Similarly, null
+               //              arguments may simply be omitted such that fewer than 4 arguments
