Reactive programming means you register a callback and a framework is responsible for calling your callback correctly. If you've understood the difference between the code, remember that reactive programming is a branch of declarative programming. It is one of programming paradigms, oriented around data flows and the propagation of change. “Programming Paradigm” sounds super pretentious and is definitely a phrase some of my college profs loved. vs Imperative Imperative vs declarative programming: which one to choose? What that helps with is a fast non-blocking code that handles almost everything going via the event-loop thread (IO thread). These two paradigms can be used together in order to serve different purposes. Many developers struggle because they try to treat an event emitter as an event queue and try to figure out how they can write a while loop to pull events from the event emitter. There is no exact right or incorrect type to use. In computer science, functional programming is a programming paradigm where programs are constructed by applying and composing functions.It is a declarative programming paradigm in which function definitions are trees of expressions that each return a value, rather than a sequence of imperative statements which change the state of the program.. The trick is that we are not working with arrays now but streams. Mostly the code we right in Java Android that is imperative and where we are going that is Reactive. by Bart Jacobs in Programming.
