Introduction to the events module in Node.js and an analogy to understand events and responses.

• Events module allows working with events in Node.js, which are actions that can trigger responses in the application.
• An analogy is presented where placing an order for a pizza is the event, and baking the pizza is the response.

Demonstration of importing the event emitter class and emitting an 'order placed' event.

• The event emitter class is imported from the events module.
• An instance of the event emitter class is created and used to emit an 'order placed' event.

Explanation of how to register listeners to respond to events using the event emitter instance.

• Listeners are registered to events using the 'on' method.
• An arrow function is added as a listener that logs 'order received' and 'baking a pizza' when the event is emitted.

Showing how to pass arguments with events and how listeners automatically receive them.

• Arguments are passed to listeners by emitting an event with additional arguments.
• A listener is shown to accept and log the size and toppings of a pizza order.

Registering multiple listeners for the same event and demonstrating the non-blocking nature of events.

• Multiple listeners can be registered for the same event.
• The non-blocking nature of event-driven programming is exemplified by adding a log statement before event emission.
