What defines the scope of a variable declared using the keyword “let”?

Write a full program that will allow a user to enter and store the names and GPAs for class of ten (10) students. You should store this information in a JavaScript object. You’ll need to keep track of the number of students entered separately (unless you can remember how to get the size of an Object without references). Create an empty JavaScript object calls “gpas”. Create a variable to keep track of the number of names and GPAs stored. This should initially be 0. While there are fewer than 10 names and GPAs in the dictionary: The program will prompt for a student’s name. If the user enters a name that is already in the “gpas” array, alert an error message to the screen that you already have that student’s GPA. Otherwise, prompt the user for the student’s GPA. Store the name and GPA in the “gpas” array. Increment the number of names stored. Return to the start of the loop. My solution is 13 lines of JavaScript. My solution did not include any validation checking and assumes all data will be entered correctly (unless otherwise stated in the description).
