Use of WebWorkers for gaming - HTML5 Game Programming question

Web workers seem like an important addition to Javascript, especially in terms of gaming. Being able to run a 'thread' to calculate say, collision detection, seems valuable. Wondering if you cover web workers in the book at all, or if they are too much a pain to use due to their limitations (no access to DOM, for ex).

Andrew,

Web Workers are covered. Web Workers communicate with the host page via message passing. If you can modularize your code in such a way to separate the computation needed on a worker thread from say the UI drawing, you won't have a problem with not accessing the DOM from the worker.

Cool, good to hear. I haven't seen a lot on web workers re: the whole 'HTML5' thing (seems like web sockets, local storage and geolocation get most of the pub) so something to look forward to in the book.

Thanks!
