How to print mongoose find() array docs in console

Question

I'm trying to use mongodb with node.js using Mongoose ODM.

I've written some sample code which is given below:

Sample Code -

/*!
 * mongoose.js
 * 
 * Getting Started
 */ 

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var db = mongoose.connect('mongodb://localhost/trymongo').connection;
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', function() {
  console.log("Connected to database");  // we're connected!
  
  // create schemas
  var SubjectSchema = new Schema({
    name: {
        type: String,
        required: true
    },
    teacher: {
        type: String
    }
  },
  {
    collection: 'subjects'
  });

  // create a model
  var Subject = mongoose.model('Subject', SubjectSchema);
  
  var arr = [{ name: 'Computer Programming', teacher: 'M. Swaminathan' }, { name: 'History' }];
  Subject.insertMany(arr, function(err) {
    if (err) throw err;
    
    console.log('Multiple subjects created!');

    // get all the subjects
    Subject.find({}, function(err, subjects) {
        if (err) throw err;
                
        console.log(subjects);
    });
  });
});

I want to print subjects in console using console.log() returned by mongoose model but it only prints like this -

[ [object Object], [object Object] ]

I've also tried with console.dir() but result is same as above.

Use console.log(JSON.stringify(subjects, null, 4))
