Write function bmi that calculates body mass index (bmi = weight / height2).
if bmi <= 18.5 return "Underweight"
if bmi <= 25.0 return "Normal"
if bmi <= 30.0 return "Overweight"
if bmi > 30 return "Obese"
function bmi(weight, height) {
let result = weight / (height * height)
if (result > 30)
return "Obese";
else if (result <= 18.5)
return "Underweight";
else if (result <= 25.0)
return "Normal";
else
return "Overweight";
}
