WHEN A SCOPE IS TERMINATED, EXPLAIN HOW MANY “DESTROY” EVENTS ARE FIRED?

When a scope is terminated, explain how many “destroy” events are fired?

2 Destroy events are fired when a scope is terminated.
The first one is an AngularJS event, “$destroy”, and the second one is a jqLite / jQuery event “$destroy”.
The first one can be used by AngularJS scopes where they are accessible, such as in controllers or link functions.
Consider the two below happening in a directive’s postLink function.
The AngularJS event: scope.$on(‘$destroy’, function () {
// handle the destroy, i.e. clean up.
});
And
element.on(‘$destroy’, function () {
// jQuery plugins already have this handler.
// angular.element(document.body).off(‘someCustomEvent’);
});
The jqLite / jQuery event is called whenever a node is removed, which may just happen without scope teardown.
