Coding Challenge #2 - BMI Comparison using if / else statements

const massMark = 78;
const heightMark = 1.69;
const massJohn = 92;
const heightJohn = 1.95;

const BMIMark = (massMark / heightMark ** 2).toFixed([1]);
const BMIJohn = (massJohn / (heightJohn * heightJohn)).toFixed([1]);
const markHigherBMI = BMIMark > BMIJohn;

// BMIMark > BMIJohn
if (markHigherBMI) {
    console.log(`Mark's BMI (${BMIMark}) is higher than John's (${BMIJohn})!`)
} else {
    console.log(`John's BMI (${BMIJohn}) is higher than Mark's (${BMIMark})!`)
}
// prints Mark's BMI (27.3) is higher than John's (24.2)!

 

참고로 여기서 소숫점 자리수를 제한하기 위해 .toFixed([digits])를 사용했다.

매개변수 digits에는 소수점 뒤에 나타날 자릿수를 지정해줌
