Functions can be used as arguments for other functions. Let's use the preceding bmi function to check whether a person has an obesity issue. According to the BMI scale, someone with a bmi between 30.0 and 54 is said to have obesity. We will pass a function as an argument, as follows:

const bmi = (weight, height) => weight / (height * height);
const hasObesity = (bmi) => bmi >= 30.0 && bmi <=54;
console.log(hasObesity(bmi(100, 2.2)));
