Assorted jQuery questions
<p>1.) What's the difference between these two queries, exactly?</p>

<pre><code>$( "#orderedlist li" )
$( "#orderedlist&gt;li" )
</code></pre>

<p>2.) In the jQuery file itself there is a function that returns the following:</p>

<pre><code>function now(){
    return +new Date;
}
</code></pre>

<p>What does that mean?  I've never seen +new before.</p>

<p><strike>3.) In a brief skimming of a tutorial, I observed the following samples:</p>

<pre><code>// use this to reset a single form
$( "#reset" ).click( function()
{
    $( "form" )[0].reset();
});

// use this to reset several forms at once
$( "#reset" ).click( function()
{
 $( "form" ).each( function()
 {
  this.reset();
 });
});
</code></pre>

<p>When I try to reference my own queries by array indexes, they don't seem to work.  Yet this example clearly did when I tested it.  What could I be doing wrong?</strike></p>

<p><strong>Edit:</strong> I'll put this one into its own question soon.
<strong>Edit 2:</strong> Actually I may be able to debug it myself.  Hang on...</p>

<p>I have guesses to each of these, but short of dissecting the jQuery file itself in full, I'm not completely certain what's at work here.  Help appreciated.</p>
