bookChallenge: Building a Class

Task

You're creating a system to manage a car rental fleet. Each vehicle has specific details: the make, model, and year. Build a Vehicle class to represent these details for each car.

  1. Create the Class: Define a class named Vehicle;
  2. Add a Constructor: Inside the Vehicle class:
    • Define a constructor that takes three parameters: make, model, and year;
    • Assign these parameters to the class properties.
  3. Create and Test Instances:
    • Create a Vehicle instance named car1 with the values "Toyota", "Camry", and 2020;
    • Create another instance named car2 with "Ford", "Mustang", and 2018;
    • Log the properties for each car instance.

class _____ { constructor(_____, _____, _____) { this._____ = _____; this._____ = _____; this._____ = _____; } } // Create instances const car1 = new _____(_____, _____, _____); const car2 = new _____(_____, _____, _____); // Output the details console.log(car1._____); // Expected: Toyota console.log(car1._____); // Expected: Camry console.log(car1._____); // Expected: 2020 console.log(car2._____); // Expected: Ford console.log(car2._____); // Expected: Mustang console.log(car2._____); // Expected: 2018

  • Define a class named Vehicle;
  • Add a constructor with three parameters: make, model, and year;
  • Inside the constructor, assign each parameter to a property using this;
  • Create an instance of Vehicle named car1 with values "Toyota", "Camry", and 2020;
  • Create another instance of Vehicle named car2 with values "Ford", "Mustang", and 2018;
  • Use console.log() to display the properties of car1 and car2.
