Just like the ReactiveX Framework, Reactor is also a fourth-generation reactive programming library. It allows you to write non-blocking reactive apps. However, it has some significant differences as compared to ReactiveX, as listed here:
- Unlike ReactiveX, which supports several platforms and languages (for example, RxSwift for Swift, RxJava for JVM, RxKotlin for Kotlin, RxJS for JavaScript, RxCpp for C++, and so on), Reactor supports only JVM.
- You can use RxJava and RxKotlin, if you have Java 6+. However, to use Reactor, you need Java 8 and above.
- RxJava and RxKotlin doesn't provide any direct integration with Java 8 functional APIs, such as CompletableFuture, Stream, and Duration, which Reactor does.
- If you're planning to implement reactive programming in Android, you have to use RxAndroid, RxJava, and/or RxKotlin (collectively...
