Observers

Observers are entities that monitor or receive updates about specific events or changes, often without directly influencing the process. Think of them as independent reporters or listeners that stay informed about a particular system or activity. In technology, for example, observers can track data changes, system status, or user actions, allowing developers to respond or analyze operations efficiently. This concept helps create modular, responsive systems where different parts can stay updated independently, enhancing flexibility and control without interfering with the core process.
