Reactive Programming
Reactive programming is a programming paradigm centered around asynchronous data streams and the propagation of change. This means that when a data value changes, all parts of a program that depend on that data are notified and updated automatically. Imagine a spreadsheet: when you change the value in one cell, any formulas that use that cell's value are instantly recalculated. Reactive programming brings this dynamic, responsive behavior to software development. This approach allows developers to build applications that are more resilient, scalable, and responsive, especially when dealing with real-time data and user interactions.
