Below, I have developed a Solitaire game using almost completely Javascript, to present my skill at programming. It has a black and a red joker that you can play on any opposite color. Once you have placed a joker you must use a card on it that fits in the stack properly, but when you move the joker off the stack you can play it on any opposite color, and you take any cards on top of it with you. To play it, click on the card that you want to move then click on the card where you want to move it to.

Programming is at the core of all computers and devices. It is instructions to the hardware of a device to perform certain actions. I remember watching an old documentary on PBS network about the first calculator ever invented. It was a set of 10 light bulbs controlled by switches. Addition was the only thing it could do, and it could count to 10. PHP and Javascript are both basically programming languages for the web. That is where you get your web based games.
I started programming software back in the early 1990's. I have a good basic knowledge of writing programs for anything that requires programming. SQL is a programming language designed to work with databases. PHP is a server side programming language that links a database to HTML and Javascript, plus more. Javascript is a programming language the runs on the clients computer, pertaining to a web browser for its base.
