Revealing constructor pattern event-emitter
// This event emitter emits events, but reserves the right to publish events to
// for its creator. It uses a WeakMap for true encapsulation.
const eesToEventMaps = new WeakMap();
export default class EventEmitter {
constructor(publisher) {
const eventMap = Object.create(null);
eesToEventMaps.set(this, eventMap);
