5. Beyond the Fundamentals

Activity 5.01: Simple Number Comparison

Solution

1. Create the function signature:

   function average_grade() {

2. Copy the function arguments to a variable. This should be a new Array instance:

       var args = Array.prototype.slice.call(arguments);

3. Sum all the values of the arguments and store them in a variable:

       var sum = 0;    for (let i=0; i<args.length; i++) {
           sum += Number(args[i]);
       }

   Remember to convert the grade values into a Number instance so that they can be correctly added together.

4. Get the average of the sum and store it in a variable:

       var average = sum / args.length;

5. Using the average, calculate the student's grade and return it. This can simply be a list of conditionals:

       if (average < 35) {
         return &quot...
