Threaded JavaScript with Web Workers
JavaScript guru (developer of JQuery among many other things) John Resig, goes into detail about “Web Workers”, a new WHATWG and W3C specification for running background JavaScript in a browser, much like the concept of threading found in many programming languages. Currently supported in Safari 4 and Firefox 3.5, it’s one of the many HTML 5 and related developments, like the new geolocation API, canvas and the like simultaneously being specified and implemented in browsers.
