var users = [
{ 'user': 'barney', 'active': true },
{ 'user': 'fred', 'active': false },
{ 'user': 'pebbles', 'active': false }
];
resolve( _.takeRightWhile(users, function(o) { return !o.active; }) );
// => ['fred', 'pebbles']
// using the `_.matches` callback shorthand
resolve( _.takeRightWhile(users, { 'user': 'pebbles', 'active': false }) );
// => ['pebbles']
// using the `_.matchesProperty` callback shorthand
resolve( _.takeRightWhile(users, ['active', false]) );
// => ['fred', 'pebbles']
// using the `_.property` callback shorthand
resolve( _.takeRightWhile(users, 'active') );
// => []
