Confused on usage of JQuery Selector reference

Ok, so as i am working on a development project, i started doing my normal object reference acquisition var obj = $(".selector"); but then noticed that when i tried to operate on this reference it was not the root object.

enter image description here

Currently have JQuery 2.1 & JQuery UI 1.10.4 in the link folder.

Any explanation as to why i have use the Index 0 to get a reference to the html control?

The jQuery selector returns a jQuery QuerySet object, which includes the set of results matching the query. It also allows you to call jQuery functions on the result, such as .text(), .addClass(), etc., instead of using the JavaScript DOM API.

As for why elements are accessible through indexing (vs, say, a property called domElement or something): remember that jQuery selector queries can return multiple elements. Imagine, for example, if you had multiple elements with the class "selector". Then wnd[0] will return the first matching DOM element, and wnd[1] will return the second matching DOM element.
