[Behavioral 5] Mediator design pattern with TypeScript example

Benefits of the Mediator Pattern:
1. Decoupling: Components don’t need to know the details of other components, reducing dependencies.
2. Centralized Control: All interaction logic is placed in the mediator, which makes it easier to change or extend.
3. Improved Maintainability: Since components only know the mediator, changes in one component are less likely to impact others.

When to Use It:
• When multiple objects interact with each other in complex ways and change the interaction logic often.
• When you want to reduce the dependencies between interacting objects.

This approach can make your system more modular and easier to maintain.
