Reactive Programming is a programming paradigm focused on asynchronous data streams and the propagation of change. It allows developers to create systems that respond to events or changes in data, making it easier to manage complex interactions and user interfaces. This approach is particularly useful in applications that require real-time updates, such as social media feeds or live data dashboards. In Reactive Programming, components react to data changes automatically, reducing the need for manual updates. Frameworks like RxJava and ReactiveX provide tools to implement this paradigm, enabling developers to handle events and data flows efficiently. This leads to more responsive and maintainable applications.
