Now that you have a connection to your MongoDB cluster, you can use the MongoDB Node.js Driver to interact with your database and perform CRUD operations. The driver allows you to easily connect to MongoDB databases from within Node.js applications. To get started, you need to install the driver using npm, create a free MongoDB Atlas cluster, load sample data, and note the connection string for your cluster. Then, you can use the `MongoClient` class to connect to your database, list the databases in your cluster, and print their names to the console. The example code includes a main function that connects to the database, lists the databases, catches any errors, closes the connection, and calls itself recursively until it runs out of iterations.
