+  //      note 1: While IE (and other browsers) support iterating an object's
+  //      note 1: own properties in order, if one attempts to add back properties
+  //      note 1: in IE, they may end up in their former position due to their position
+  //      note 1: being retained. So use of this function with "associative arrays"
+  //      note 1: (objects) may lead to unexpected behavior in an IE environment if
+  //      note 1: you add back properties with the same keys that you removed
+  //   example 1: array_pop([0,1,2])
+  //   returns 1: 2
+  //   example 2: var $data = {firstName: 'Kevin', surName: 'van Zonneveld'}
+  //   example 2: var $lastElem = array_pop($data)
+  //   example 2: var $result = $data
+  //   returns 2: {firstName: 'Kevin'}
