How does mongoose.ObjectId work?

mongoose.ObjectId is a built-in constructor function in the Mongoose library for generating and validating MongoDB ObjectIds, which are unique identifiers used to identify documents in MongoDB collections. It can also be used to convert a string representation of an ObjectId into a proper ObjectId instance.

const mongoose = require("mongoose");

const objectIdString = "612e9805d90b4f5d7e63d3d4";
const objectId = mongoose.Types.ObjectId(objectIdString);

console.log(objectId); // Output: 612e9805d90b4f5d7e63d3d4

In this example, we're first requiring the mongoose library. We then create a string that represents an ObjectID (objectIdString). We can then use mongoose.Types.ObjectId to convert this string to an ObjectId object (objectId). We can then log the resulting ObjectId object to the console.
