What's the difference when new operator is applied?
<p>For example, if I would like to display the current date on the <code>p</code> element:</p>

<pre><code>$("p").html('Now is '+Date()); // good
$("p").html('Now is '+new Date()); // good
$("p").html(Date()); // good
$("p").html(new Date()); // bad
</code></pre>

<p>Why the last statement does not display the current date, but the second statement works?</p>
