Javascript expando objects
<p>What are expando objects in javascripts? </p>

<p>For what purpose we need this ? Any complete example will be appreciated</p>

<p>I found 1 article here <a href="http://it.toolbox.com/blogs/think-clients/javascript-the-redheaded-stepchild-of-web-development-18471">Javascript: The red-headed stepchild of web development</a></p>

<p>Thanks </p>
