RxJS Aggregates Module
The Reactive Extensions for JavaScript has a number of aggregation operators including those you might already know from the Array#extras and the upcoming ES6 standard such as reduce
, find
and findIndex
. This module is used exclusively for aggregation operations used on finite observable sequences. In addition to the aforementioned operators, there are many useful operators such as count
, sum
, average
and determining whether two sequences are equal via the sequenceEqual
method. This requires rx.lite.js
from the rx-lite
NPM module.
Getting Started
There are a number of ways to get started with RxJS.
Installing with NPM
```bash` $ npm install rx-lite-aggregates $ npm install -g rx-lite-aggregates
### Using with Node.js and Ringo.js
```js
var Rx = require('rx-lite-aggregates');
In a Browser:
<!-- Just the core RxJS -->
<script src="path/to/rx.lite.js"></script>
<script src="path/to/rx.lite.aggregates.js"></script>

Contributing
There are lots of ways to contribute to the project, and we appreciate our contributors. If you wish to contribute, check out our style guide.
You can contribute by reviewing and sending feedback on code checkins, suggesting and trying out new features as they are implemented, submit bugs and help us verify fixes as they are checked in, as well as submit code fixes or code contributions of your own. Note that all code submissions will be rigorously reviewed and tested by the Rx Team, and only those that meet an extremely high bar for both quality and design/roadmap appropriateness will be merged into the source.
