객체(Object) - 생성자함수(construction function)

같은 객체의 반복 -> template의 필요성

let apple = {
    name : 'apple',
    price : 100,
    'color' : 'greed',
    display : function(){
        console.log(`${apple.name} :🍏`);
    }
}

let banana = {
    name : 'banana',
    color : 'yellow',
    display: function(){
        console.log(`${this.name} : 🍌`)
    }
}

let cherry = {
    name : 'cherry',
    color : 'red',
    display: function(){
        console.log(`${this.name} : 🍒`)
    }
}

생성자함수(template)

function Fruit(name, color, emogi){
    this.name = name;
    this.color = color;
    this.emoji = emogi;
    this.display = function(){
        console.log(`${this.name} : ${this.emoji}`);
    }
    return this;
}

const cherry = new Fruit("cherry","red","🍒");
const grape = new Fruit("grape", "purple", "🍇");
const melon = new Fruit("melon", 'light green', '🍈');

정해진 템플릿을 이용하여 원하는 데이터를 전달

console.log(cherry);
console.log(grape);
console.log(melon.display());
