記得//你的大名歐

var myBMI = weight / (height * height);

return myBMI;
}

getBMI(1.5, 50);

var BMI = getBMI(1.5, 50);

因為作業的題目是getMessage函式可以傳入height與weight，所以這邊建議把bmi放到函式內，並讓getMessage傳入height與weight兩個參數，然後在getMessage內呼叫getBMI，例如:

function getMessage(height,weight){
    var BMI=getBMI(height,weight);
        ......
}

if ( BMI < 18.5 ){
console.log('體重過輕');
}else if(18.5 <= BMI && 24 > BMI){
console.log('正常範圍');
}else{
console.log('異常範圍');

這邊再console.log(getMessage(1.5,50));印出結果就好
