Q.

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"

A)

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";
}
