Should I Use Schema.Types.ObjectId or Schema.ObjectId When Defining a Mongoose Schema

Question

It seems like defining my Schema this way:

var PossessionSchema = new mongoose.Schema({   thing: {type: mongoose.Schema.Types.ObjectId, ref:"Thing"} }); 

or this way:

var PossessionSchema = new mongoose.Schema({   thing: {type: mongoose.Schema.ObjectId, ref:"Thing"} }); 

Both work. I see that the mongoose guide uses Schema.Types.ObjectId

http://mongoosejs.com/docs/schematypes.html

But I'm confused that both work.

Which one should be used for the Schema? And what is the difference between the two?

It doesn't matter. Both is exactly the same. If you actually console.log(mongoose.Schema); you can see that both mongoose.Schema.ObjectId and mongoose.Schema.Types.ObjectId refer to the exact same thing.

{ [Function: Schema]   reserved: {      _posts: 1,     _pres: 1,     validate: 1,     toObject: 1,     set: 1,     schema: 1,     save: 1,     modelName: 1,     get: 1,     isNew: 1,     isModified: 1,     init: 1,     errors: 1,     db: 1,     collection: 1,     once: 1,     on: 1,     emit: 1    },   interpretAsType: [Function],   Types: {      String: { [Function: SchemaString] schemaName: 'String' },     Number: { [Function: SchemaNumber] schemaName: 'Number' },     Boolean: { [Function: SchemaBoolean] schemaName: 'Boolean', '$conditionalHandlers': [Object] },     DocumentArray: { [Function: DocumentArray] schemaName: 'DocumentArray' },      Embedded: [Function: Embedded],     Array: { [Function: SchemaArray] schemaName: 'Array' },     Buffer: { [Function: SchemaBuffer] schemaName: 'Buffer' },     Date: { [Function: SchemaDate] schemaName: 'Date' },     ObjectId: { [Function: ObjectId] schemaName: 'ObjectId' },     Mixed: { [Function: Mixed] schemaName: 'Mixed' },     Oid: { [Function: ObjectId] schemaName: 'ObjectId' },     Object: { [Function: Mixed] schemaName: 'Mixed' },     Bool: { [Function: SchemaBoolean] schemaName: 'Boolean', '$conditionalHandlers': [Object] }    },   ObjectId: { [Function: ObjectId] schemaName: 'ObjectId' }  }
