  { 'user': 'fred',    'active': false },
  { 'user': 'pebbles', 'active': false }
];
 
_.takeRightWhile(users, function(o) { return !o.active; });
// => objects for ['fred', 'pebbles']
 
// The `_.matches` iteratee shorthand.
_.takeRightWhile(users, { 'user': 'pebbles', 'active': false });
// => objects for ['pebbles']
 
// The `_.matchesProperty` iteratee shorthand.
_.takeRightWhile(users, ['active', false]);
// => objects for ['fred', 'pebbles']
 
// The `_.property` iteratee shorthand.
_.takeRightWhile(users, 'active');
// => []
