为什么会恢复正常体重

Question

This BMI calculator returns it right for the underweight and the normal weight, but when result is bigger than 25 it returns the normal weight option, when it's supposed to return the overweight option. How can I fix it?

 function bmiCalculator(weight, height) { var weight = prompt("How much do you weight?") var height = prompt("How tall are you? ") result = weight / Math.pow(height, 2) if (result < 18.5) { return("Your BMI is " + result + ", so you are underweight") } else if (result >= 18.5 || result <= 24.9) { return("Your BMI is " + result + ", so you have a normal weight") } else if (result >= 25) { return("Your BMI is " + result + ", so you are overweight") } } console.log(bmiCalculator())

Answer 1

You just need to change the || to an &&

Instead of:

} else if (result >= 18.5 || result <= 24.9) {

Do:

} else if (result >= 18.5 && result <= 24.9) {
