Write a function that calculates a user BMI. BMI = weight/height[s]^[/s]2 Your code should request for the user's weight and height and then return their bmi to them. Your return statement should be "[BMI]kg/m[s]^[/s]2.
P.S: To simplify, use prompt and alert (depending on how your language calls it) when necessary and make sure your code is testable on the Google Chrome console (developer tool)

const weight = prompt("Enter your weight");
const height = prompt("Enter your height");
const bmiCalc = () => {
const bmi = weight / Math.pow(height, 2);
return `Your BMI is ${bmi}kg/m^2`;
};
alert(bmiCalc());

@"mccall"#p963 this looks interesting, this looks like ES 5 syntax right?

The solution in python is:
[s]`[/s]def bmi_calc(weight, height):`
[s]` [/s]bmi = weight / (height ** 2)`
[s]` [/s]return f"Your BMI is {bmi} kg/m^2"`
[s]`[/s]weight = float(input("Enter your weight: "))`
[s]`[/s]height = float(input("Enter your height: "))`
[s]`[/s]print(bmi_calc(weight, height))`
[s]`[/s]def bmi_calc(weight, height):`
[s]` [/s]bmi = weight / (height ** 2)`
[s]` [/s]return f"Your BMI is {bmi} kg/m^2"`
[s]`[/s]weight = float(input("Enter your weight: "))`
[s]`[/s]height = float(input("Enter your height: "))`
[s]`[/s]print(bmi_calc(weight, height))`
