Swap Two Numbers in JavaScript

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 mobile number here in the Philippines is 09173084360.

My telephone number at home here in Bacolod City, Negros Occidental is (034) 4335675.
