I am doing a standard task with codewares: Write function bmi that calculates body mass index (bmi = weight / height2).
Here is my solution:
function bmi(weight, height) {
let bmi = weight / (height ** 2)
if (bmi <= 18.5) {
return "Underweight";
} else if (bmi <= 25.0) {
return "Normal"
} else if (bmi <= 30.0) {
return "Overweight"
} else if (bmi > 30) {
return "Obese"
}
}
console.log(bmi(80, 1.80))I have a question: is it possible to solve this problem with the help of a switch? Because I tried it in different ways and in the console I have undefined:
function bmi(weight, height) {
let bmi = weight / (height ** 2)
let c = "Normal"
switch (bmi) {
case "Underweight":
bmi <= 18.5;
break;
case "Normal":
bmi <= 25.0;
break;
case "Overweight":
bmi <= 30.0;
break;
default:
return;
}
}
console.log(bmi(80, 1.80))>Solution :
You have switched your case and your outcome– that’s the issue. Here it is switched the right way:
function bmi(weight, height) {
let bmi = weight / (height ** 2)
let c = "Normal"
switch (bmi) {
case bmi <= 18.5:
c = "Underweight";
break;
case bmi <= 25.0:
c = "Normal";
break;
case bmi <= 30.0:
c = "Overweight";
break;
}
return c;
}
console.log(bmi(80, 1.80))
