What does the eventListeners property add to all angular 2+ nodes?

Question

Angular

I recently learned that all nodes in an agular have an eventListeners property. This is a function that returns an array of all handlers that are attached to the element. A quick google did not help to understand what this property hangs on the node node.

DebugElement can also access this list of listeners, you can use it in tests.
