lowInventory({'milk':14,'butter':5,'bread':37,'jam':8}) must return 2

lowInventory{{'oil':16,'filter':29,'grease':42,'hydraulic fluid':18}) must return 0

function lowInventory(dictionary){
    count = 0;
    for (var key in dictionary) {
        if (dictionary.hasOwnProperty(key)) {
            if(dictionary[key]<10)
                count++;
        }
    }
    return count;
}
