15. JavaScript CLASS !

😝 원래 JavaScript에는 클래스가 따로 존재하지 않는데, ES6부터 클래스가 생겼다!

✨ 일반적인 function

function Health(name) {
  this.name = name;
}

Health.prototype.showHealth = function() {
  console.log(this.name + "님, 안녕하세요");
}

const h = new Health("damoo");
h.showHealth();

🔎 console

---

"damoo님, 안녕하세요"

✨ class

모습만 class 이지, prototype으로 구현된다.

class Health {
  constructor(name, lastTime) {
    this.name = name;
    this.lastTime = lastTime;
  }
  
  showHealth() {
    console.log("안녕하세요, " + this.name + "님");
  }
}

const myHealth = new Health("damoo");
myHealth.showHealth();
console.log(toString.call(Health));

🔎 console

---

"안녕하세요, damoo님"
"[object Function]"
