Reactive Extensions (Rx) is a library for composing asynchronous and event-based programs using observable sequences and LINQ-style query operators.
Data sequences can take many forms, such as a stream of data from a file or web service, web services requests, system notifications, or a series of events such as user input.
Reactive Extensions represents all these data sequences as observable sequences. An application can subscribe to these observable sequences to receive asynchronous notifications as new data arrive.
|Single return value||Multiple return values|
|Pull/Synchronous/Interactive||Object||Iterables(Array | Set | Map)|
To put it more concretely, if you know how to program against Arrays using the Array#extras, then you already know how to use RxJS!

Curious on how we designed RxJS? This is covered along with overall guidelines of how your RxJS code should operate. In addition, we have contribution guidelines which set the bar for which we accept contributions.
Getting to Know RxJS Libraries
rx.lite.js, but you may find you need more operators, so you start with
rx.js and add additional files to mix in functionality as you need it.
