오늘은 클래스를 제대로 알아보고 써보고자 클래스를 정리해 보았다.


class Drinks {
  constructor(name, color, milk) {
    this._name = name;
    this.color = color;
    this.milk = milk;
  }

  get name() {
    return this._name;
  }
  set name(value) {
    this._name = value;
  }

  static dairyFree(milk) {
    return milk ? `This drink contains milk!` : `This drink is Dairy Free!`;
  }

  print() {
    return `This is ${this.name}. The color should be ${this.color}.`;
  }
}


class Coffee extends Drinks {
  constructor(name, color, milk, caffeine) {
    super(name, color, milk);
    this.caffeine = caffeine;
  }

  print() {
    return super.print() + ` This contains caffeine.`;
  }
}

class Soda extends Drinks {
  // constructor에 추가할 것 없으면 적을 필요 없음
  sparkling() {
    return `${this._name} is a sparking drink.`;
  }
  
}


const coffee = new Coffee('Latte', 'brown', true, true);
const sprit = new Soda('sprit', 'transparent', false);

console.group('check class');
console.log(coffee);
console.log(coffee.print());
console.log(sprit);
console.log(sprit.print());
console.groupEnd('check class');

console.group('check static');
console.log(Drinks.dairyFree(coffee.milk));
console.log(Drinks.dairyFree(sprit.milk));
console.groupEnd('check static');

console.group('check get set');
sprit.name = 'fanta';
console.log(sprit.name);
console.groupEnd('check get set');
