mongoose ObjectId != mongo ObjectId ??

app.js

var mongodb = require('mongodb');
var	mongoose = require('mongoose');
var id = '51a11f2d4da20b020000000a';
var mongooseId = new mongoose.Types.ObjectId(id);
var mongoId = new mongodb.ObjectID(id);
var logs = [];
if(mongoId == mongooseId){
    logs.push('mongoId == mongooseId');
}
else{
    logs.push('mongoId != mongooseId');
}
if(mongoId === mongooseId){
    logs.push('mongoId === mongooseId');
}
else{
    logs.push('mongoId !== mongooseId');
}
console.log(logs.join(', '));

For me, this outputs:

mongoId != mongooseId, mongoId !== mongooseId
