Readonlysession
Readonlybubbles
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.
cancel
Readonlycancelable
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.
Readonlycomposed
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.
Readonlycurrent
Returns the object whose event listener's callback is currently being invoked.
Readonlydefault
Returns true if preventDefault() was invoked successfully to indicate cancelation, and false otherwise.
Readonlyevent
Returns the event's phase, which is one of NONE, CAPTURING_PHASE, AT_TARGET, and BUBBLING_PHASE.
Readonlyis
Returns true if event was dispatched by the user agent, and false otherwise.
return
Readonlysrc
Readonlytarget
Returns the object to which event is dispatched (its target).
Readonlytime
Returns the event's timestamp as the number of milliseconds measured relative to the time origin.
Readonlytype
Returns the type of event, e.g. "click", "hashchange", or "submit".

Methods
composed
composedPath(): EventTarget[]Returns the invocation target objects of event's path (objects on which listeners will be invoked), except for any nodes in shadow trees of which the shadow root's mode is "closed" that are not reachable from event's currentTarget.
Returns EventTarget[]
init
prevent
preventDefault(): voidIf invoked when the cancelable attribute value is true, and while executing a listener for the event with passive set to false, signals to the operation that caused event to be dispatched that it needs to be canceled.
Returns void
stop
stopImmediatePropagation(): voidInvoking this method prevents event from reaching any registered event listeners after the current one finishes running and, when dispatched in a tree, also prevents event from reaching any other objects.
Returns void
stop
stopPropagation(): voidWhen dispatched in a tree, invoking this method prevents event from reaching any objects other than the current object.
XRSessionEvents are fired to indicate changes to the state of an XRSession. ref: https://immersive-web.github.io/webxr/#xrsessionevent-interface
