The Observer pattern is a powerful design pattern that promotes a one-to-many dependency between objects. This pattern is particularly useful in scenarios where changes in one object need to be reflected across multiple objects. A classic use case for the Observer pattern is in building a notification system, where subscribers (observers) are notified of changes in a publisher (subject). In this
