Now that we have some destructuring in place, we can easily pull more things off of MongoDB. We can add a comma and specify something else we want to pull off. In this case, we're going to pull off uppercase, ObjectID.
const {MongoClient, ObjectID} = require('mongodb');
This ObjectID constructor function lets us make new ObjectIds on the fly. We can do anything we like with them. Even if we're not using MongoDB as our database, there is some value in creating and using ObjectIds to uniquely identify things. Next, we can make a new ObjectId by first creating a variable. I'll call it obj, and we'll set it equal to new ObjectID, calling it as a function:
const {MongoClient, ObjectID} = require('mongodb'); ...
