the Chain of Responsibility

The Chain of Responsibility is a design pattern that distributes a request along a chain of potential handlers. Each handler examines the request; if it can handle it, it does so. If not, it passes the request to the next handler in the chain. This approach helps manage different types of requests smoothly without hardcoding decision logic in one place, making systems more flexible and easier to maintain. It’s commonly used in software development to organize how tasks or messages are processed across multiple components or services.
