Observe Pattern

The Observe Pattern is a design approach in software development where objects, called observers, automatically receive updates when another object, called the subject, changes its state. Think of it like a subscription system: when the main data or event changes, all interested parties are notified without needing to constantly check for updates. This pattern promotes loose coupling, meaning the subject doesn't need to know the details of its observers, making the system more flexible and easier to maintain. It's commonly used in user interfaces, event handling, and real-time data updates.
