constructor.js

//Simple implementation of a class using a the ES6 defined constructor function, showing inheritance

//using Vehicle Class to inherit property from
class Vehicle {
  constructor(color){
    this._color = color;
  }
}

//Car inherits from Vehicle class 
class Car extends Vehicle{
  constructor(color,make, model, year){
    //super must be implemented before the child class properties.
    super(color)
    this._make = make;
    this._model = model;
    this._year = year;

  }
  //using a get to return this._ values with get keyword method.
  
  get make(){
    return this._make.toUpperCase();    
  }
  get model(){
    return this._model
  }
  get year (){
    return this._year;
  }

  set year(year){
    this._year = year;
  }
}

car = new Car("Red","Ford", "F-150", 1999);

console.log(car.model);
car.model = "F-250";
console.log(car.model); //do to the set method not being used car.model == 'F-150'
console.log(car.year);
car.year = 2018;
console.log(car.year)//2018, it worked, that old 99 was beat out.
