A program that I wrote using JavaScript that will ask the user to give a number and then our program will compute it's factorial equivalent value. The code is very simple and easy to understand.
I am currently accepting programming and web development work kindly contact me in the following email address for further details. Thank you.
My email address are the following jakerpomperada@gmail.com and jakerpomperada@yahoo.com.
My telephone number at home here in Bacolod City, Negros Occidental is (034) 4335675.
