bmi

Language/Type: JavaScript parameters

Write a function named bmi that takes two Number values representing the weight and height of an individual. The function should calculate the body mass index (BMI), using the following formula: 

BMI = weight / height2 * 703

The BMI rating groups each person into one of the following four categories:

BMI Category
below 18.5 class 1
18.5 - 24.9 class 2
25.0 - 29.9 class 3
30.0 and up class 4

After calculating the bmi and class for the given weight and height, your function should output the results, matching the following example output for the call to bmi(70.0, 194.25): 

BMI = 27.9
class 3

Use the console.log() function to print each line of output and n.toFixed(1) to get a string of a number n to the precision of one decimal point. For example, if n is 1.2345, n.toFixed(1) would return "1.2".
