declare namespace EventEmitter {
  type Callback<T = any> = (data: T) => void;
}

declare const EventEmitter: {
  /**
   * Emits an event with data (Angular-style)
   */
  emit<T = any>(event: string, data: T): void;

  /**
   * Dispatches an event with data (Redux-style)
   */
  dispatch<T = any>(event: string, data: T): void;

  /**
   * Subscribes to an event
   */
  subscribe<T = any>(event: string, callback: EventEmitter.Callback<T>): void;
};

export = EventEmitter;
