13~18行應該放到getMessage函式中判斷，每個判斷都要return一個訊息，例如:
if(bmi<18.5){
return "過輕";
}
| } | ||
| console.log(getBMI(1.88, 74)); | ||
| // getMessage | ||
| var message ; |
| // getMessage | ||
| var message ; | ||
| function getMessage(height, weight){ | ||
| return weight/(height*height); |
| function getMessage(height, weight){ | ||
| return weight/(height*height); | ||
| } | ||
| var bmi= getMessage(1.7,74) |
| message='過重' } | ||
| else{ | ||
| message='正常'} | ||
| console.log(message); // |

console.log(getMessage(1.7,74));印出函式結果就可以了
