Fra og med 30.01.2020. Se den nyeste version.

Adds a listEventListeners method to every element that returns an array containing every event added to that listener.

Eg.

const el = document.getElementById("my-test-element");
el.addEventListener("click", doSomething);
el.listEventListeners(); // returns [doSomething]
