RxJS is the ReactiveX implementation for JavaScript.

It was an implementation of the watcher pattern. After its development, later programming libraries were developed around major languages such as .NET and JavaScript.

The ReactiveX project was originally started by Matthew Podwysocki and others as an independent open source project for Microsoft.

It was then quickly used by companies like Netflix with RxJava.

Currently the main maintainer of RxJS is Ben Lesh. (previously developer at Google and Netflix)
