html5-displayDavid Rousset describes how you can write JavaScript to take advantage of the new dual- or quad-core processors in your HTML5 applications. You’ll be interested in this for several kinds of scenarios, such as:

  • image processing
  • big amount of data 
  • background text analysis
  • concurrent requests against a local database
  • and more.

His article, Introduction to the HTML5 Web Workers: the JavaScript multithreading approach, shows step by step how you can implement HTML5 Web Workers with some cool demo and sample code.

Web Workers have just arrived in the IE10 PP2 (Platform Preview). This is also supported by Firefox (since 3.6), Safari (since 4.0), Chrome & Opera 11. However, this is not supported by the mobile versions of these browsers. If you’d like to have a more detailed support matrix, have a look here: http://caniuse.com/#search=worker
