How ES6 hoisting works

hoisting.mjs

/**
 * Hoisting does not work; The userLicenseFactory method is not hoisted to the top.
 * @throws {ReferenceError} ReferenceError: Cannot access 'User' before initialization
 */
// console.log(User);

/**
 * Hoisting works; The {UserFunc} method is hoisted to the top.
 */
console.log(UserFunc);

/**
 * Hoisting does not work; The userFactory variable is not hoisted to the top.
 * @throws {ReferenceError} ReferenceError: Cannot access 'User' before initialization
 */
// console.log(userFactory);

/**
 * Hoisting works; The {userLicenseFactory} method is moved to the top.
 */
console.log(userLicenseFactory);

/**
 * This constant does not get hoisted.
 */
const userFactory = () => User;

/**
 * This function is hoisted.
 */
function userLicenseFactory() {
  return UserLicense;
}

/**
 * Hoisting does not work.
 * @throws {ReferenceError} ReferenceError: Cannot access 'UserLicense' before initialization
 */
// userLicenseFactory();

/**
 * This class is not hoisted.
 */
class User {

  }
}

/**

// const user = new User();

/**

 */
class UserLicense {

/**
 * This function is hoisted, hoisting works.
 */
function UserFunc() {
}
