That should work as expected:

        keys: ['xyz','foo']
    },{
        item: 'b',
        keys: ['xwt','bar']
    }];

    _filtered = items.filter(function(item) {
        return item.keys.indexOf(_key) != -1

        return item.item;
    });
    return !!_filtered.length ? _filtered[0] : false;
}
