Testing

The helper.js file is tested with qUinit and you can see the test suite at http://skorecky.github.com/JShelper/test/

This file is also regurally tested at http://jshint.com

How to Use

Simply include helper.js in your html file before anything that calls it.

<script type="text/javascript" src="https://raw.github.com/skorecky/JShelper/master/helpers.min.js"></script>

It's written in pure JavaScript so it should work nicely with any JS Framework / Library.
