-// Below are the steps for how BMI is calculated
-
-// The BMI calculation divides an adult's weight in kilograms (kg) by their height in metres (m) squared.
-
-// For example, if you weigh 70kg (around 11 stone) and are 1.73m (around 5 feet 8 inches) tall, you work out your BMI by:
-
-// squaring your height: 1.73 x 1.73 = 2.99
-// dividing 70 by 2.99 = 23.41
-// Your result will be displayed to 1 decimal place, for example 23.4.
+function calculateBMI(weight, height) {
+  // Square the height (height in meters)
+  const heightSquared = height * height;
 
-// You will need to implement a function that calculates the BMI of someone based off their weight and height
+  // Divide weight by height squared to get BMI
+  const bmi = weight / heightSquared;
 
-// Given someone's weight in kg and height in metres
-// Then when we call this function with the weight and height
-// It should return their Body Mass Index to 1 decimal place
+  // Return the BMI rounded to 1 decimal place
+  return bmi.toFixed(1); // toFixed returns a string, which is fine unless you need it as a number
+}
 
-function calculateBMI(weight, height) {

+// Example usage:
+console.log(calculateBMI(70, 1.73)); // Output: "23.4"
