Overview
Reactive programming is about building systems that respond to events or changes in data. It is particularly useful for building highly responsive and scalable applications, such as real-time dashboards or streaming services.
Key Concepts
- Observables: Streams of data that can be observed.
- Observers: Components that react to changes in observables.
- Operators: Functions used to transform, filter, or combine streams.
- Backpressure: A mechanism to handle situations where the data producer is faster than the consumer.
Popular Libraries
- RxJS (JavaScript)
- Project Reactor (Java)
- Akka (Scala/Java)
