JAVASCRIPT:

Please create an array of student names and another array of student grades.
- Create a function that can put a name and a grade to the arrays.
- Keep Read student name and grade until student name is “???”. And save the reading by using a function
- Create another function to show all the grade in that object.
- Create the third function that can display the maximum grade and the student’s name.
- Create a sorting function that can sort the arrays based on the student’s grade.
- Display all the grades and names sorted by the grade.

Please modify the JavaScript code (HTML) below to meet the requirements, and submit it. Also submit a screenshot of the output.
