// === 2 === // implement type type User = any;

The User type can be defined by describing the structure of an object with the necessary fields. For example, if a user has a name, email, and age, the type can be described as:

type User = {
  id: number;
  name: string;
  email: string;
  age?: number; // optional field
};

This allows using the User type for strict type-checking of user data in the application.
