how to do user already there update ? if not there create in particular collection using node,express,mongodb?

when i run these

Log.find(function(err, logs) {
        if (err) {
            return handleError(res, err);
        }
        console.log(logs);
});

i got the below documents

var logs = [{
                mobilenumber : '1',
                ref : 3,
                points : 1000,
                ctype : 'mycredit',
                entry : 'sdfsdf',
                entry : 0
        },{
                mobilenumber : '1',
                ref : 6,
                points : 2000,

                entry : 0
        },{

        }];
        
        var summary = [];
        var positive = 0, negative = 0, total = 0, count=0;
        for(var i = 0; i<logs.length; i++){
                count = 0;
                positive = 0;
                negative = 0;
                total = 0;
                
                for(var j = i; j<logs.length; j++){
                        if(logs[i].mobilenumber === logs[j].mobilenumber){
                                if(logs[j].points < 0){
                                        negative += logs[j].points;
                                }
                                else if(logs[j].points >= 0){
                                        positive += logs[j].points;
                                }
                                
                                total += logs[j].points;
                                count++;
                        }
                }
                i+=count-1;
                var obj = {
                        mobilenumber : logs[i].mobilenumber,
                        positivepoint : positive,
                        negativepoint : negative,
                        balancepoints : total
                }
                summary.push(obj);
        }
        
        console.log("summarylist = ", summary);
        
        var giftList = [];
        
        for(var i = 0; i<summary.length; i++){
                var mod = Math.floor(summary[i].balancepoints / 1000);
                
                for(var j = 0; j<mod; j++){
                        var obj = {
                                mobilenumber : summary[i].mobilenumber,
                                gifed_id : 1,
                                ref :'gifted',
                                gifed_point : 1000,
                                active : true
                        }
                        summary[i].balancepoints -= 1000;
                        summary[i].negativepoint -= 1000;
                        giftList.push(obj);
                }
        }
        console.log("giftlist = ", giftList);

when ever user reaches 1000 point i created new giftcard and store it on gift collection .

Every time i am calculating the user 'positivepoint' ,'negativepoint' and 'balancepoints' of all user and everything is working fine

if you run the above code you will get two object lists 'summarylist' and 'giftlist'

Now i want update summarylist data into summary collection

Summary.find(function(err, Summary) {
        if (err) {
            return handleError(res, err);
        }
        console.log(Summary);
});

i got below documents

summary collection already has three documents

{
    "_id": {
        "$oid": "59118950aae3ab641f2d01b6"
    },
    "mobilenumber": "1",
    "positivepoint": 1000,
    "negativepoint": 0,
    "balancepoints": 1000,

},
{
    "_id": {
        "$oid": "950aae591183ab641fb62d01"
    },
    "mobilenumber": "10",
    "positivepoint": 100,
    "negativepoint": -10,
    "balancepoints": 90,

},
{
    "_id": {
        "$oid": "183950aae591ab62d01641fb"
    },
    "mobilenumber": "14",
    "positivepoint": 1000,
    "negativepoint": 0,
    "balancepoints": 1000,

}

now i want to update mobilenumber 1 and 10 documents and

i want to insert mobilenumber 2 and 11

how can i query and get the below result expected summary collection

{
    "mobilenumber": "1",
    "positivepoint": 4000,
    "negativepoint": -3000,
    "balancepoints": 1000,

},
{
    "mobilenumber": "2",
    "positivepoint": 2600,
    "negativepoint": -2500,
    "balancepoints": 100,

},
{

    "mobilenumber": "10",
    "positivepoint": 900,
    "negativepoint": -10,
    "balancepoints": 890,

},
{

    "mobilenumber": "11",
    "positivepoint": 110,
    "negativepoint": 0,
    "balancepoints": 110,

},
{

    "mobilenumber": "14",
    "positivepoint": 1000,
    "negativepoint": 0,
    "balancepoints": 1000,

}
