Question 1 Enter student grades using the prompt() window.The notes entered will be stored progressively in an array identified as <notes>.Be careful, check that each note entered is a number. No non-numeric values will be stored in the array.
Question 2 Write a bestNote() JS function that takes an array as a parameter and returns the maximum of this array.
Question 3 Write a JS function numSuccesses() which takes an array as parameter and returns the number of array elements greater than or equal to 60. This method calculates the number of students who passed.
Question 4 Write a JS function nbFailures() which takes an array as a parameter and uses the nbSuccess() method to calculate and return the number of failures, i.e. the number of scores lower than 60.
Question 5 Write a JS sum() function that takes an array as a parameter and returns the sum of the array elements.
Question 6 Write an average() JS function that takes an array as a parameter and uses the sum() method to calculate and return the average of the scores. The average is the sum of the scores divided by the number of scores.
Question 7 Write a JS mention() function that takes as input an integer n and returns a string as follows:If n < 60, returns "Failed"If 60 <= n < 70, returns "Average"If 70 <= n < 80, returns "Good"If 80 <= n < 90, returns "Very good"If 90 <= n , returns "Excellent"
