JavaScript Inheritance Exercise: Restaurant Booking System with Customer Service Bot

Context and Overview

This exercise aims to help understand object-oriented programming in JavaScript by creating a restaurant booking system with classes and inheritance. Additionally, they will build a customer service bot that interacts with users to facilitate bookings.

User Stories

Basic Restaurant Class

• As a developer, I want to create a basic Restaurant class so that I can use it as a base for various types of restaurants.

Specialized Restaurant Types

• As a developer, I want to extend the Restaurant class to create specific restaurant types (e.g., FineDining, CasualDining, Cafe) that have unique properties and methods.

Booking Class

• As a system admin, I want to have a Booking class that can track the customer name, date, time, and number of guests so that the restaurant can manage reservations effectively.

Inheritance for Special Bookings

• As a developer, I want to create specialized booking types (e.g., GroupBooking, EventBooking) by extending the Booking class to cater to specific needs like group sizes or events.

Traveler Class

• As a developer, I want to create a Traveler class to manage information about people traveling, including name, origin, and destination, so they can interact with bookings and restaurants.

Interaction Between Classes

• As a user, I want to be able to assign bookings to different types of restaurants, manage traveler details, and retrieve information about the bookings, the travelers, and the restaurant.

Exercise Outline

Create a brand new repo and create a node project

Part 1: Setting Up the Base Classes

• Task 1: Create a Restaurant class with properties like name, address, cuisineType, and methods such as describe() which prints out a description of the restaurant.
• Task 2: Create a Booking class with properties including customerName, date, time, and numberOfGuests, and methods like bookingDetails() that outputs reservation details.
• Task 3: Create a Traveler class with properties like name, origin, and destination, and a method to display traveler details.

Part 2: Implementing Inheritance

• Task 4: Extend the Restaurant class to create different types of restaurants. For instance, FineDining might include additional properties like dressCode.
• Task 5: Extend the Booking class to create GroupBooking and EventBooking, adding properties like groupSize or eventType, with methods that override or extend the base class functionalities.
• Task 6: Extend the Traveler class for specific types of travelers, such as BusinessTraveler or Vacationer, adding specific needs and behaviors.

Part 3: Interaction and Simulation with Customer Service Bot

• Task 7: Install and utilize the prompt-sync module to create interactive prompts for the customer service bot.

npm install prompt-sync

• Task 8: Develop a script where the bot prompts the user to choose a type of restaurant, enter booking details, and interact with the system to make a reservation.
• Task 9: Use console logs to simulate the bot’s interaction, such as confirming a booking or suggesting alternative options based on the user’s input.

Expected Learning Outcomes

By the end of this exercise, apprentices should be able to:

• Understand and apply JavaScript class syntax and constructors.
• Implement inheritance in JavaScript using extends and super.
• Integrate user input into a system using Node.js and prompt-sync.
• Develop interactive scripts that simulate real-world applications like a customer service bot.
