What is an event bus and how does it work?

An event bus is a design pattern used to facilitate communication between different components in a system. It allows for decoupled communication, meaning that components can send and receive messages without needing to know about each other directly.

Can you explain the benefits of using an event bus?

Sure! The benefits include improved modularity, easier maintenance, and the ability to handle asynchronous events efficiently.

What are some common use cases for an event bus?

Common use cases include handling user interactions in web applications, managing state changes in microservices, and integrating different systems in an event-driven architecture.

How do I implement an event bus in my application?

You can implement an event bus by creating a central hub that listens for events and dispatches them to the appropriate handlers. Libraries like Node.js EventEmitter or frameworks like Spring provide built-in support for this.
