How to define an objectId type in mongoose 6.0.0^

I am seeing many answers saying that the correct way to define an objectId type in a mongoose schema is like:

type: mongoose.Schema.Types.ObjectId

But from the mongoose docs they show that you can define an objectId type like so:

const carSchema = new mongoose.Schema({ driver: mongoose.ObjectId });

Is there something I am missing? What is the correct way to define an objectId type? Are both methods correct or one is outdated?

Both of these roads lead to Rome, there is no single "correct" way.

The type is defined in https://github.com/Automattic/mongoose/blob/master/lib/schema/index.js#L24 as

exports.ObjectId = require('./objectid');

The rest are the pointers to this export. Some are shorter, some are longer unless you use them in the context.

The mongoose.Schema.Types.ObjectId comes from there: https://github.com/Automattic/mongoose/blob/master/lib/schema.js

Schema.Types = MongooseTypes = require('./schema/index');

mongoose.ObjectId comes from https://github.com/Automattic/mongoose/blob/master/lib/index.js#L940

Mongoose.prototype.ObjectId = SchemaTypes.ObjectId;
