In this article I would like to share with you a simple program that I wrote using JavaScript to ask the user to give number integer numbers and then our program will swap the arrangement of the two numbers.
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.
