You are tasked with developing a real-time notification system in Node.js. Which feature of the Events module would be most beneficial in implementing this?

  • event.emitOnce()
  • event.removeAllListeners()
  • event.once()
  • event.removeListener()
In a real-time notification system, you would want to ensure that each notification is only sent once to the respective listeners. The event.once() method allows you to do this as it automatically removes the listener after it's been invoked once, ensuring efficient and clean handling of notifications. The other options are useful for managing listeners but do not guarantee a one-time notification.
