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

There are some difference between the two:

• Using nested schema is helpful for validation.

• Nested schema can be reused in other schemas.

• Nested schema add '_id' field to the subdocument unless you used "_id:false"
