Hackerrank Grading Students Problem's Solution in JavaScript

HackerLand University has the following grading policy: Every student receives a grade in the inclusive range from 0 to 100 . Any grade less than 40 is a failing grade. Sam is a professor at the university and likes to round each student's according to these rules: If the difference between the grade and the next multiple of 5 is less than 3, round grade up to the next multiple of 5. If the value of grade is less than 38, no rounding occurs as the result will still be a failing grade. Examples Grade =84 round to (85 - 84 is less than 3) Grade =29 do not round (result is less than 40) Grade =57 do not round (60 - 57 is 3 or higher) Given the initial value of grade for each of Sam's n students, write code to automate the rounding process.
