How to use the Mongoose function from mongoose

mongoose.Mongoose is a class in the Mongoose library that provides an interface for creating MongoDB database connections and defining data models.

How does mongoose.Mongoose work?

mongoose.Mongoose is a class constructor that creates a new instance of the Mongoose class, which is a MongoDB object modeling tool designed to work in an asynchronous environment with Node.js. It allows developers to define schemas for data collections and provides methods for querying and manipulating data in MongoDB databases. When mongoose.Mongoose is invoked, it returns a new Mongoose instance that can be used to connect to MongoDB and interact with data in various ways.

  });

// Define a schema for a "user" document
const userSchema = new mongoose.Schema({
  name: String,
  age: Number,

});

// Create a "User" model based on the "user" schema
const User = db.model("User", userSchema);

// Create a new user document
const user = new User({
  name: "John Doe",
  age: 30,
  email: "john.doe@example.com",
});

// Save the user document to the database
