Write a JAVASCRIPT program that will help an elementary school student learn multiplication. Use the Random method to produce two positive one-digit integers. The program should then prompt the user with a question using random numbers, such as How much is 6 times 7? The student then inputs the answer. Next, the program checks the student’s answer. If it is correct, display the message "Very good!" and ask whether the student wants to continue if so then ask another multiplication question. If the answer is wrong, display the message "No. Please try again." and let the student try the same question repeatedly until the student finally gets it right. A separate method should be used to generate each new question. This method should be called once when the program begins execution and each time the user wants to continue.
