express js how to convert an array to an object

This is my user model so you guys can get an idea of my database structure.

var userSchema = new Schema({
firstName: {type: String, required: true, trim: true},
lastName: {type: String, required: true, trim: true},
address: {
    street: {type: String, required: true, trim: true},
    city: {type: String, required: true, trim: true},
    state: {type: String, min: 2, max: 2, required: false},
    zipCode: {type: String, required: true, trim: true},
},
companies:[
    {
        type: Schema.Types.ObjectId,
        ref: 'Company',
        required: true
    }
],
edited: {type: Date},
created: {type: Date, default: Date.now}
});

I'm trying to get the user and the companies related to that user. which im getting with this.

router.post('/', function(req, res){

var email = req.body.email;
var password = req.body.password;


User.findOne({email: email, password: password, active: true})
    .populate('companies')
    .exec(function(err, user){

    if(err){
        throw err;
    }
    else if (!user) {
        //user wasn't found
        res.render('/', {validation: "Invalid Email Or Password"})
    }
    else {

        user.companies = user.companies[0];

        console.log(user);

        res.end();

    }

});
});

when in the console.log(user) i'm getting this output:

{
    firstName: 'firstName',
    lastName: 'lastName'
    companies:[{object}]
}

now the problem with my code is that im saying that the companies array should be an object in this line of code.

user.companies = user.companies[0];

my question is how can I make the console output be like this.

    {
    firstName: 'firstName',
    lastName: 'lastName'
    companies:{object}
}

It seems that user variable is immutable, you can create another object and copy its data to new object 

var _user = {
    firstName: user.firstName,
    lastName: user.lastName
    companies: user.companies[0]
}

OR

simply use toObject() function to convert mongodb object to plain object, so you can modify it

user = user.toObject()
