Answer 1

$and jQueryis a function that contains properties.

JQuery source contains string

window.jQuery = window.$ = jQuery

It establishes $and jQueryto refer to the same object (which is a function)

The source also sets the properties of this object, for example

jQuery.each = function(...) { ... };
