Node.js loop through array doesn't show entire objects

I have found strange behavior of array in Node.js

Googling didn't help. Ofc, it may cause of my fatigue. If so, I am sorry.

So, my model

var UserSchema = new mongoose.Schema({
    id: mongoose.Schema.ObjectId,
    added: {
        type: Date,
        default: Date.now()
    },
    displayName: String,
    cart: [{
        orderNumber: mongoose.Schema.ObjectId,
        exposition: Object,
        offer: Object,
        state: Number,//1 - Unpaid
    }],
});

In controller I am trying to loop through cart array

    var cartId = new ObjectId(req.body.id);
    mongoose.model('User').findById(currentUser.userId, function (err, user) {
        var cart = user.cart;
        console.log(cart);
        var expId = -1;
        if (cart) {
            for (var i = 0; i < cart.length; i++) {
                var cartItem = cart[i];
                console.log(cartItem);
                if (cartItem._id === cartId) {
                    console.log("SHIT");
                    expId = user.cart.exposition._id;
                    break;
                }
            }
        }
    });

I didn't find better solution to find embedded cart in user than loop. So, when I am logging my cart object

console.log(cart);

I am getting correct object and it works ok, but when I am trying to log 

console.log(cartItem);
console.log(cart[0]);

I am getting only

[object Object]
[object Object]

What am I doing wrong?

Problem:

This problem arises because you are using findById() which returns result inside the array

According to my knowledge, there can be only one user record inside User document

Solution: Use findOne() which return a single user result, and you can iterate through user.carts

That is the default toString() for an object. Try

console.log(JSON.stringify(cartItem));
console.log(JSON.stringify(cart[0]));

instead if you want to see the structure of the object.
