const mongoose = require('mongoose');

​

// Assuming you have an ObjectId

const objectId = new mongoose.Types.ObjectId();

​

// Convert ObjectId to string

const objectIdString = objectId.toString();

​

console.log('ObjectId:', objectId);

console.log('ObjectId as String:', objectIdString);

The following example calls the valueOf() method on an ObjectId():

​

ObjectId("507c7f79bcf86cd7994f6c0e").valueOf()

​

This will return the following string:

​

507c7f79bcf86cd7994f6c0e

​

You can confirm the type of this object using the following operation:

​

typeof ObjectId("507c7f79bcf86cd7994f6c0e").valueOf()
