how to find recent record of record matching particular criteria

    {
"_id" : ObjectId("5514ecc73910d3e808b9417c"),
"endingReciptBookNumber" : 2999,
"startingReciptBookNumber" : 2900,
"User" : 8,
"allRecipt" : [ 
    {
        "recipt_Number" : 2999,
        "amount" : 24124,
        "_id" : ObjectId("5514ecc73910d3e808b94180")
    }, 
    {
        "recipt_Number" : 100,
        "amount" : 2414,
        "_id" : ObjectId("5514ecc73910d3e808b9417f")
    }, 
    {
        "recipt_Number" : 101,
        "amount" : 242,
        "_id" : ObjectId("5514ecc73910d3e808b9417e")
    }, 
    {
        "recipt_Number" : 102,
        "amount" : 2424,
        "_id" : ObjectId("5514ecc73910d3e808b9417d")
    }
],
"__v" : 0

}

I have many documents like this in a collection in mongoose .I want to find a latest entered recipt_Number for a particular user. like in this case it should give me 102 as answer.

i have also attached snippet of lines of code. Its also a way to get same result. 

db.topics.find( {'User': 8}, { 'allRecipt': { $slice: -1 },'startingReciptBookNumber':0,'endingReciptBookNumber':0,'User':0,'_id':0,'__v':0 } )

query result like below

{
    "allRecipt" : [ 
        {
            "recipt_Number" : 102,
            "amount" : 2424,
            "_id" : ObjectId("5514ecc73910d3e808b9417d")
        }
    ]
}

Though query won't give any single number in result but it will give desired outcome through result.allRecipt.0.recipt_Number, Your desired number will always get into in 0 index. I think this is your desired number.

Here $slice make a difference.

Thanks
