Symfony Event Dispatcher

The Symfony Event Dispatcher is a tool that allows different parts of an application to communicate and react to specific actions or changes. Think of it as a centralized hub where events (like a user login or data update) are announced, and various listeners (pieces of code) can respond accordingly. This system promotes loose coupling, meaning components don’t need to directly know about each other, making the application more flexible and easier to maintain. Essentially, it helps manage and coordinate actions smoothly within the application, enhancing modularity and scalability.
