Mongodb Nested Query Returns Only Last Occuring Result

Okay, I have this code containing a nested query inside a for loop var query = records.find({$or:[{starter:data},{receiver:data}]},{});//check the records table for all persons the

Solution 1:

To navigate the js async, I did some to and fro emitting with socket.io and it worked

on the server side

var query = records.find({$or:[{starter:data},{receiver:data}]},{});//check the records table for all persons the logged in user has spoken to
query.sort('-createDate').exec(function (err, docs){
    if(err) throw err;

    for(var i=docs.length-1; i>= 0; i--)
    {

       var starter  = docs[i].starter;
        var receiver = docs[i].receiver;
        var lasttxt = docs[i].lastMessage; 

        if (starter == socket.usernames){
          var target = receiver;
        }else
        {
          var target = starter;
        }

      var userlast = target+" "+lasttxt;
                socket.emit('lastly', userlast);//Emit the username and last message for the client to emit back here
    }
})

On your client side, Pick up the emitted data

 socket.on('lastly', function(data){//Recieve the data and send right back
                  socket.emit('lastly2', data);
              });

Back on you server side, pick up the data sent back

socket.on('lastly2', function(data){//receive the username and last message to work withvar check = data;
var space = check.indexOf(' ');
var name = check.substr(0, space);
var msg = check.substr(space+1);

usersrec.find({username:name},{}).lean().exec(function (errx, docx){
            if(errx) throw errx;

            docx[0].message = msg;
            socket.emit('usernames', docx);
      });

Yeah its probably unorthodox, but at least it gets the job done. Im open to better suggestion tho
