What is Reactive Programming?
Updated May 6, 2026
Short answer
Reactive Programming is a paradigm focused on asynchronous data streams and propagation of changes.
Deep explanation
It enables systems to react to data changes automatically. Instead of pulling data, components subscribe to streams and get pushed updates. It is widely used in UI frameworks and event-driven systems.
Real-world example
Live stock price updates in a trading app.
Common mistakes
- Confusing reactive programming with multithreading.
