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

The Reactive Extensions for JavaScript Lite version is a lightweight version of the Reactive Extensions for JavaScript which covers most of the day to day operators you might use all in a single library.  Functionality such as bridging to events, promises, callbacks, Node.js-style callbacks, time-based operations and more are built right in.

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