Description: The Chain of Responsibility pattern is a design pattern that allows an object to send a command without knowing which object will receive and handle it. This pattern is based on the idea that a message can be processed by one or more objects in a chain, where each object has the option to handle the message or pass it to the next in the chain. This promotes decoupling between the sender and receiver of the message, facilitating the addition of new handlers without modifying existing code. The main features of this pattern include flexibility in assigning responsibilities, the ability to create dynamic chains of handlers, and improved code organization by avoiding the need for multiple conditionals to determine which object should handle a message. In JavaScript, this pattern can be implemented using functions and objects, allowing developers to create more scalable and maintainable systems. Its relevance lies in its ability to efficiently manage requests, especially in applications where multiple objects may be responsible for handling different types of requests, such as in event handling systems or general error management.
