         'bar',
         'baz',
-    ],
-    'bar' => [

-        'quux' => 'quuz',
     ],
 ];

Example 2

Configuration:

• direction: 'desc'

-    ],
     'foo' => [
         'foo',
         'bar',
         'baz',
+    ],

+        'quz' => 'qux',
+        'quux' => 'quuz',
     ],
 ];

     'QuZ' => 'qux',
     'quz' => 'qux',
-    'Quux' => 'quuz',
-    'quux' => 'quuz',
 ];
