Alias for emitter.removeListener().
The emitEvent method is a public method for emitting events, with an optional configuration that allows
+middleware processing. Middleware functions can intercept and transform the event before it reaches the listeners,
+allowing custom validation or data modifications.
This method enables flexible event emission with support for middleware, providing a robust event processing
+mechanism in the BaseEventEmitter. It’s useful for customizing event behavior based on application-specific needs.
