[Node.js] mongoose의 비동기식 처리

때문에...

[javascript]
app.get('/p/:id/:title', function(req, res){
var to = req.params.id;
var disCount, diffCount, likeCount, sameCount, queCount, allCount;
Comments.find({'to':to, 'emotion':'불만이 있습니다.'}).count(function(err, count){
disCount = count;
Comments.find({'to':to, 'emotion':'다르게 생각합니다.'}).count(function(err, count){
diffCount = count;
Comments.find({'to':to, 'emotion':'좋아합니다.'}).count(function(err, count){
likeCount = count;
Comments.find({'to':to, 'emotion':'공감하고 있습니다.'}).count(function(err, count){
sameCount = count;
Comments.find({'to':to, 'emotion':'궁금해 합니다.'}).count(function(err, count){
queCount = count;
Comments.find({'to':to}).count(function(err, count){
allCount = count;
res.render('presentation', {'port':port, 'username':req.session.username, 'p_id':req.params.id, 'title':req.params.title,'disCount':disCount, 'diffCount':diffCount, 'likeCount':likeCount, 'sameCount':sameCount, 'queCount':queCount, 'allCount':allCount});
});
});
});
});
});
});
});
[/javascript]

이게 뭔짓인가 싶네요.. 뭔가 깔끔한 방법 없을까요? ㅠㅠ
