Write a Javascript program that will ask user to enter a number in a prompt window then ask user to enter 2nd number in a prompt window. Once the numbers are entered, the program will generate the consecutive sum and product from first number to second number (for example, if 1 and 5 is entered, the sum should output 15 and product 120.

Note: Assume the values entered by user will be smaller than 100 and the range (the difference between first number and second number) no more than 20.

Please write full working program.

Thanks.
