Event Bus

An Event Bus is a system that helps different parts of an application communicate with each other efficiently. Imagine a public transportation bus that carries messages instead of people. When something happens in one part of the system (like a user clicking a button), it can send a message (an event) to the bus. Other parts of the application can listen for these messages and respond accordingly. This decouples the various parts, allowing them to work independently while still sharing important information, which makes the application more organized and easier to maintain.
