ost game programs follow the same recipe—the game must gather input from the user, process that input and any other data, and render objects to the screen. Usually, the program creates event handlers that listen for user input via the mouse, keyboard, or other input device, and a game loop that manages data processing and rendering the display. Once launched, the game loop continues until it encounters some end condition.

In this article, I'll create a simple demo called Rebound that should get you started with game programming in JavaScript. Rebound is a simple ball and paddle game where the user controls a paddle with the keyboard and must keep a moving ball from getting beyond the paddle. You can view the demo here.
