What is the purpose of the Mediator design pattern?

The purpose of the Mediator design pattern is to promote loose coupling between objects by encapsulating their communication logic within a central mediator object. This pattern allows objects to communicate with each other indirectly through the mediator, reducing the dependencies between them and making the system more maintainable and extensible. The mediator acts as a coordinator, facilitating communication and coordination between objects without them having direct knowledge of each other.
