Every call to jQuery or its alias $ actually produces a new, unique object instance from a real constructor. The example you gave produces a constructor that wraps a handful of instance method definitions along with several function declarations - which I'm arguing could just as easily be outside of that function declaration, but inside of an IIFE.
