Unhandled NaN error

Error Description: The code is throwing a NaN error when calculating the BMI for certain input values.

Context: The error occurs when the user enters invalid input values for height or weight. In some cases, the height value may be zero or negative, resulting in a division by zero or a negative number. In other cases, the weight value may be a non-numeric value, such as a string or null, causing the calculation to fail.

Steps to Reproduce:
Enter a height value of zero or a negative number.
Enter a weight value that is not a number, such as a string or null.
Click the "Calculate" button to trigger the BMI calculation.
Observe that the BMI result displays as NaN.

Relevant Information: The code snippet for the BMI calculation is included below:

let height = document.querySelector('#height').value;
let weight = document.querySelector('#weight').value;

if (height == '' || weight == '') {
  alert('Please fill out the input fields!');
  return;
}

height = height / 100;

let BMI = weight / (height * height);

BMI = BMI.toFixed(2);

Labels and Milestone: This issue could be labeled as a bug and assigned to a milestone for the next release.
