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).

Explain the difference between a JavaScript library and a JavaScript framework. Is Vue a library or a framework? Defend your answer.

How do we display the contents of a variable in the Virtual DOM of a Vue application? (Assume the variable is named “variable” for the answer.)

Write the JavaScript code that will create/declare an array named “intervals” that is initially empty. Use a FOR loop to populate that array with the sequence 2, 4, 6, 8, 10, 12 (every element goes up by another 2). At the end of the FOR loop, the list should have 6 elements. Here’s how to lose points on this question: – The array is not initially empty.- At the end of the program, the array does not have 6 elements.- The elements are not as described above.- The program does not populate the array from within a FOR loop.

What is the function used to initialize the data in our Vue application?
