Declaring variables javascript
<p>I just have a quick question and cant find anything on google. I was going through some code another programmer put together and he declares ALL of his javascript variables with $ in front of them...for instance:</p>

<pre><code> var $secondary;
</code></pre>

<p>Is there a reason for this? Could this cause problems in the future if JQuery ever ends up being used. I'm just curious because I was going to clean it up if so.</p>
