To implement the event emitter class, I will create a JavaScript class called EventEmitter. This class will have methods for subscribing to events, unsubscribing from events, and emitting events. The class will use an internal data structure like a dictionary to keep track of the event subscribers. When an event is emitted, all the subscribers for that event will be called with any relevant data.
