# This is RxJS v 4. [Find the latest version here](https://github.com/reactivex/rxjs)
# RxJS Main Module #

The Reactive Extensions for JavaScript's main functionality is in the main RxJS file which has many core components including the Schedulers, Disposables, Observable and Observer.

This comes with both `rx.js` which is for use in modern development environments such as > IE9 and server-side environments such as Node.js.  We also have `rx.compat.js` which has backwards compatibility to browsers which do not support all required ES5 features.
