how to add default value to array containing object in mongoose schema

Question

I have a mongoose schema like this - now the default keyword in url field works but how do i set a similar default value to only id field in the comments section?

var feedSchema = mongoose.Schema({
    url:{type:String, unique:true, default: uuid.v4()},
    comments:[{
        id:String,
        text:String,
        username:String
    }],
});

Use an object to define the id field so that you can provide a default for it:

var feedSchema = mongoose.Schema({
    url:{type:String, unique:true, default: uuid.v4()},
    comments:[{
        id: {type: String, default: '55'},
        text:String,
        username:String
    }],
});

How would you define a default value for comments? e.g.: comments will be [] (empty array).

@Deerloper It would be best to post that as a new question.
