When jQuery creates new wrapper object for element(s)?
<p>Can anybody tell me, if I call ex. </p>

<pre><code>var obj1 = $('#element_id')
var obj2 = $('#element_id')
</code></pre>

<p>will obj1 refer to the same javascript object as obj2 does, or there will be 2 different objects, having the same HTML element they wrap?</p>

<p>And what about complex selectors, like ('.my_class, .my-class2'), which wrap collection of objects?</p>
