MDN Reference
no setter
atTarget → num: Available on Event, provided by the Event$Typings extension

no setter
bubbles → bool: Available on Event, provided by the Event$Typings extension
Returns true or false depending on how event was initialized. True if event goes through its target's ancestors in reverse tree order, and false otherwise.
no setter

MDN Reference
no setter
cancelable → bool: Available on Event, provided by the Event$Typings extension
Returns true or false depending on how event was initialized. Its return value does not always carry meaning, but true can indicate that part of the operation during which event was dispatched, can be canceled by invoking the preventDefault() method.

no setter
composed → bool: Available on Event, provided by the Event$Typings extension
Returns true or false depending on how event was initialized. True if event invokes listeners past a ShadowRoot node that is the root of its target, and false otherwise.
