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.
