Weekend Assignment: Car Marketplace Management System

Objective:

Your task is to create a JavaScript program that manages a car marketplace. This system should be able to handle different entities such as car agencies, customers, and a tax authority. The car marketplace data will be provided to you. All actions will be executed with console outputs.

Requirements:

Your JavaScript program should be able to perform the following functionalities:

1. Agency Operations:

   • Search for a car agency by its name or ID.
   • Retrieve all agencies' names.
   • Add a new car to an agency's inventory.
   • Remove a car from an agency's inventory.
   • Change the cash or credit of an agency.
   • Update the price of a specific car in an agency (Method: updateCarPrice).
   • Calculate and return the total revenue for a specific agency (Method: getTotalAgencyRevenue).
   • Transfer a car from one agency to another (Method: transferCarBetweenAgencies).

2. Customer Operations:

   • Search for a customer by their name or ID.
   • Retrieve all customers' names.
   • Change the cash of a customer.
   • Calculate the total value of all cars owned by a specific customer (Method: getCustomerTotalCarValue).

3. Car Operations:

   • Retrieve all cars available for purchase.
   • Search for cars based on certain criteria. The search parameters should include the production year, price, and optionally, the brand of the car.
   • Return the most expensive car available for sale (Method: getMostExpensiveCar).
   • Return the cheapest car available for sale (Method: getCheapestCar).

4. Car Purchase Operations:

   • Implement a sellCar function that sells a car to a specific customer. This function should:
     • Check the availability of the car at the agency.
     • Verify if the customer has enough cash to purchase the car.
     • Update the cash and credit for both the agency and the customer accordingly.
     • Update the tax authority's records.
   • Calculate and return the total revenue of the entire market (Method: getTotalMarketRevenue).

Notes:

• Make sure to handle possible edge cases, for example, when a car or a customer doesn't exist, or when a customer doesn't have enough cash to buy a car.
• Remember to break down your code into manageable and logically separated functions for better readability and maintainability.
• Comment your code appropriately to describe the functionality of your methods.

Good luck!
