What is the Chain of Responsibility design pattern used for?

The Chain of Responsibility design pattern is used to create a chain of objects, where each object in the chain has the ability to handle a specific request. This pattern allows multiple objects to have a chance to handle the request, and the request is passed along the chain until it is handled or reaches the end of the chain. This pattern promotes loose coupling between the sender and receiver of a request, and allows for dynamic addition or removal of handlers in the chain.
