JavaScript-Chess,
a didactic open source chess program by Bill Jordan, written in JavaScript to run in a web browser. JavaScript-Chess is available on GitHub ¹ - an ebook explaining the program is available from Amazon ². The JavaScript code, executed in the background by a web worker, is embedded in a HTML document of a web page which implements the graphical user interface, to render a 2D graphics board with pieces using jpeg images, and to allow user and web worker interaction through message passing.
