### 객체 생성자 표기법 객체 + 함수

```javascript
function obj5(a,b){
    this.a = a;
    this.b = b;
    this.c = function(){
        return a * b;
    }
}

let result1 = new obj5(100,200);
let result2 = new obj5("자바스크립트가"," 실행되었습니다.");

document.write(result1.a,"<br>");  // 100
document.write(result1.b,"<br>");  // 200
document.write(result1.c(),"<br>"); // 20000
document.write(result2.a,"<br>");  // 자바스크립트가
document.write(result2.b,"<br>");  // 실행되었습니다.
document.write(result2.a + result2.b,"<br>"); 
// 자바스크립트가 실행되었습니다.
```

### 객체 생성자 함수

```javascript
function CheckWeight(name, height, weight){
    this.userName = name;
    this.userHeight = height;
    this.userWeight = weight;
    this.minWeight;
    this.maxWeight;
    this.getInfo = function(){
        let str = "";
        str += "이름: " + this.userName + ", ";
        str += "키: " + this.userHeight + ", ";
        str += "몸무게: " + this.userWeight + ", ";
        return str;
    }
    this.getResult = function(){
        this.minWeight = (this.userHeight - 100) * 0.9 - 5;
        this.maxWeight = (this.userHeight - 100) * 0.9 + 5;

        if( this.userWeight > this.minWeight && this.userWeight <= this.maxWeight){
            return "정상 몸무게입니다."
        } else if( this.userWeight < this.minWeight ){
            return "살좀 찌세요~.";
        } else {
            return "살좀 빼세요~.";
        }
    }
}

let park = new CheckWeight("박",179,90);
let kim = new CheckWeight("김",154,55);

document.write(park.getInfo());
document.write(park.getResult());
```
