TL;DR Laravel provides an elegant way to decouple business logic from actual processing through events, a notification mechanism that allows other parts of the application to be informed about significant occurrences without direct dependencies. An event is triggered and listened to by different components, allowing specific actions to be performed. To create a new event, define it in the app/Events directory, then create a listener responsible for processing it and register the listener in the EventServiceProvider. Finally, trigger the event from within your application using the event() helper function.
