What is reactive programming?

Reactive programming is a declarative programming paradigm like functional, modular, procedural, or object-orientated programming (OOP). A programming paradigm is a set of rules and principles specifying how you write your code. It is similar to architectural and design patterns, but they operate on a different level of abstraction.

Programming paradigms are high-level concepts that dictate the overall style, structure, and approach to writing code, whereas architectural and design patterns provide reusable templates or blueprints for structuring code, handling communication between components, managing relationships, and solving other common design challenges within your code base.

Reactive programming deals with data streams and the propagation of changes. In simple terms, reactive programming dictates how you handle events and data changes that can happen at any given time, also known as asynchronous changes. As the name already implies, you are...
