observablet

Observablet is a conceptual framework that describes a system or entity capable of emitting signals or changes that can be detected and responded to by other parts of the system or external observers. The core idea revolves around the concept of observability, meaning that the internal state or behavior of an Observablet can be inferred or known by examining its outputs.

In a typical Observablet pattern, an entity maintains a certain state. When this state changes, or when a specific event occurs within the entity, it emits a notification. This notification is often in the form of an event, a message, or a direct signal. Other entities, known as observers or subscribers, can register their interest in these notifications. Upon receiving a notification, the observer can then take a predefined action, such as updating its own state, triggering another process, or performing a calculation.

This pattern promotes loose coupling between components. The Observablet does not need to know who its observers are, or even if it has any. It simply performs its function and announces its changes. Similarly, observers do not need intimate knowledge of the Observablet's internal workings; they only need to understand the nature of the signals it emits. This separation of concerns makes systems more modular, easier to maintain, and more adaptable to change. Common applications include event-driven architectures, user interface frameworks, and real-time data processing systems.
