Is using the increment operator in javascript discouraged?
<p>I've seen code like the following in some JS libraries: </p>

<pre><code>var i;
for (i = 20; i &gt;= 0; i -= 1) 
{
}
</code></pre>

<p>I wonder why they would choose to decrement <code>i</code> in this fashion. Is there something problematic about using <code>++</code> and <code>--</code> in javascript?</p>
