Object Creation Methods

What pattern enables object communication?

const createObservable = (target) => {
  const observers = new Set();
  
  return {
    ...target,
    subscribe(observer) {
      observers.add(observer);
    },
    notify(data) {
      observers.forEach(observer => observer(data));
    }
  };
};

Command Pattern
Mediator Pattern
Observer Pattern
This implements the Observer pattern: 1) Enables one-to-many dependencies, 2) Loose coupling between subjects and observers, 3) Dynamic subscription management, 4) Consistent notification mechanism, 5) Scalable event handling, 6) Common pattern for implementing event-driven systems.
