👉 Observer computing is a programming paradigm that emphasizes the design of systems to observe and react to changes in their environment or internal state without being explicitly programmed for every possible scenario. It involves creating observers—components that monitor specific objects or states—and notifying them when these states change. This approach promotes modularity, scalability, and maintainability by decoupling the system's core logic from its external influences, allowing for easier updates and extensions. In essence, observer computing focuses on enabling systems to dynamically respond to events or data changes, enhancing their adaptability and efficiency in complex, evolving environments.
