Random programming post || factorial in a range || javascript

Hey you guys, i am a programming freak and i keep on solving some problems that comes into my mind.
I thought of why not sharing here with my fellas out here who might be interesting.
Combining programming with computer sciences is always an interesting this to do. Like finding factorial to a number, and to make it little interesting finding factorial of numbers in a range.

It ran and asked for first number

Prompted for the second number when first number was added. and then showed the results in the form of a table.

These results are for the range 2 to 8.

and the code for this is in this file
