JavaScript Exercises: Async and Functional

My U.S. Scores

Develop a JS program to convert the scores of your exams into the U.S. system
Using the functional approach, you should manage a list of objects that includes the following information about the exams:
- Course Code, Course Name, CFU, Score (a number between 18 and 30)
Create a new list with the same information but the scores according the U.S. system, where:
- 27+ -> A, 24-26 -> B, 19-23 -> C, 18 -> D
Then, compute the weighted average, considering A as 4.0 and D as 1.0
Print all your scores (in both formats), and the computed average

A possible solution: us-scores.js

Update the "Courses and Scores" exercise to use a database.
Manage a list of objects and related DB tables that include information about the exams:
- Course Code, Course name, CFU
- Attained score (number between 18 and 30, plus a Boolean for the laude)
- Date
The list of Exam objects, named ExamList, will have the following methods, operating on the DB, which return Promises:
- add(exam) // pass a fully-constructed Exam object
- getAll() // returns (a Promise that resolves to) an ExamList with all the Exams
- find(courseCode) // returns (a Promise that resolves to) the matching Exam
- afterDate(date) // returns (a Promise that resolves to) an ExamList with the subset of Exams after the given date
- getWorst(num) // returns (a Promise that resolves to) an ExamList with the num Exams with the lowest score
