Array elements vs properties?
<p>So to follow up a previous question;</p>

<p>Due to the dynamic functionality of using properties and iterating with </p>

<pre><code>for(var key in array)
</code></pre>

<p>I've used this quite a lot in favor of trying to enumerate an array and iterating by numbers.</p>

<p>What are the pro's and cons of just .pushing elements and setting as properties instead?</p>

<p>Apart from the obvious identification differences that is.</p>
