Reactive programming describes a design paradigm that relies on asynchronous programming logic to handle real-time updates to otherwise static content. Now that we know how a reactive program executes, one can say that Reactive programming is a programming paradigm in which APIs, libraries and language features are used in a specific design pattern with the goal of achieving an async reactive program execution. For example Android folks, especially since the introduction of Kotlin, have seen a rise in popularity around RP.
