Each object should have properties for: quiz name (string) mark earned (number) total marks possible (number) Use different values for this, don't just make them all out of the same mark. 2. Use the .forEach() method to add a property "percent" to each quiz object. 3. Use the .sort() method to sort the array from highest percent to lowest. 4. Each quiz is weighted equally. Calculate the average of all the percent properties using the .reduce() method. Output each quiz name and percent, rounded to an integer, on a separate line per quiz. Do this without using a loop. 6. Output the final average percent, shown to one decimal place, with some descriptive text.
