Modify the code of Question 1 to request the times table to be displayed from the user; the code should continue to request and display times tables until the user enters -1. Additionally, do a check to make sure that the user is entering a valid number; if the number is not valid, ask the user to re-enter it.

Data from Question 1

Change the code of Question 2 from Chapter 3 so that it’s a function that takes as parameters the times table required and the values at which it should start and end. For example, you might try the 4 times table displayed starting with 4 * 4 and ending at 4 * 9.

Data from Question 2 from Chapter 3

Using document.write(), write code that displays the results of the 12 times table. Its output should be the results of the calculations.
