Mongoose subdocuments vs nested schema

Question

I\'m curious as to the pros and cons of using subdocuments vs a deeper layer in my main schema:

var subDoc = new Schema({
  name: String
});

var mainDoc = n         


        

Answer 1

Basically, create a variable nestedDov and put it here name: [nestedDov]

Simple Version:

var nestedDoc = new Schema({
  name: String
});

var mainDoc = new Schema({
  names: [nestedDoc]
});
