An event is an activity or occurrence recognized and handled by the program. Events in Laravel provide simple observer implementations which allow us to subscribe and listen for events within our application. The event classes are stored in app/Events, while their listeners are stored in app/Listeners of our application. These can be generated using Artisan console commands. A single event may contain multiple listeners that do not depend on each other.

There are some events examples in Laravel which are:

A new user is registered.
A new comment is posted.
User login/logout.
A new product is added.
