jQuery – get javascript object

jQuery when applied on a css selector, returns a wrapper object which contains 0 or more javascript objects. To get the javascript object from it, we can take its 0-indexed item.

<pre id="msg"></pre>

var $jqObject = $(".box");
var jsObject = $jqObject[0];
if (jsObject) {
