How to encapsulate jQuery?

Question

Particularly I want to define local jQuery (var jQuery) where
jQuery should be stored (and also local $).

The problem is that jQuery operates directly with windo

You can pass true to $.noconflict() to have jQuery remove all its variables from the global scope:

(function($) {
    var jQuery = $.noconflict(true);
    // From there on, window.jQuery and window.$ are undefined.
    var $ = jQuery;
    // Do something with the local jQuery and $...
})(jQuery);
