The answer comes from clearing this misconception:

The jQuery library is not a property of Javascript: Instead, it's a library that builds an abstraction over most of the inconsistencies across JS engines and DOM implementations in browsers, and it must be loaded (either inline or as an external JS file) in order for scripts to use the jQuery object and its methods.
(There is a very small library in all ECMAScript implementations, including the global objects Object, Function, Boolean, String, Number, and Math, but that's a different concept from host objects as in the DOM, and from external libraries like jQuery.)
