jQuery object are immutable?
<p>Hello a new noob on jQuery here and I was wondering if jQuery objects are immutable. 
For example:</p>

<pre><code>var obj1 = $("&lt;tag&gt;&lt;/tag&gt;");
var obj2 = obj1.append("something");
</code></pre>

<p>Will obj1 and obj2 be the same meaning obj2 will reference obj1? </p>

<p>UPDATE:</p>

<p>The above example kind of scratches the surface of what i want to know, a more accurate question is : If i chain function from the jQuery api will they return the same object or a new one (as the case with strings in Java)?</p>
