What is the purpose of the Chain of Responsibility design pattern?

The purpose of the Chain of Responsibility design pattern is to create a chain of objects, where each object has the ability to either handle a request or pass it on to the next object in the chain. This pattern allows multiple objects to have the opportunity to handle a request, without the sender needing to know which object will ultimately handle it. It promotes loose coupling between sender and receiver, and allows for dynamic and flexible handling of requests.
