What is ["null"] in javascript?
<p>I am migrating an asp code to .net. I came across the following code but not sure what is it doing.</p>

<pre><code>var collection = {};
if (typeof(collection["null"]) != "undefined" &amp;&amp; 
    typeof(collection["null"][id]) != "undefined")
</code></pre>

<p>Can any well tell that what does collection["null"] does? If possible, how to define it in .Net</p>

<p>Just to give an idea, I made closedMealArea as a List in .Net</p>

<p>Thanks in advance</p>

<p>Cheers,
wildanjel</p>
