use-cc-etc ====================== This requires using ``Cc`` rather than ``Components.classes``, and the same for ``Components.interfaces``, ``Components.results`` and ``Components.utils``. This has a slight performance advantage by avoiding the use of the dot. Examples of incorrect code for this rule: ----------------------------------------- .. code-block:: js let foo = Components.classes['bar']; let bar = Components.interfaces.bar; Components.results.NS_ERROR_ILLEGAL_INPUT; Components.utils.reportError('fake'); Examples of correct code for this rule: --------------------------------------- .. code-block:: js let foo = Cc['bar']; let bar = Ci.bar; Cr.NS_ERROR_ILLEGAL_INPUT; Cu.reportError('fake');
