Student-Grade-Generator-Toy-Problem

This is a Student Grade Generator that prompts the user to input student marks. The input is between 0 and 100 which stands as the minimum and maximum score every students can score. Then the output of the respetive grade is given below: A > 79, B - 60 to 79, C - 59 to 49, D - 40 to 49, E - less 40. I used Javascript to wire down the solution.
