Code: Flickr Developer Blog » Web workers and YUI.
It’s really hard to list the modern browser enhancements in order of awesomeness, but in my opinion Web workers are right up there near the top. JavaScript-powered apps are enhancing, and from my point of view the world has accepted them as good. At a base level though they can only get so performant. Web workers turns that concept on its head, and it’s something we should all take a look at and implement at least in our development environments to really get an understanding of what they do as we progress to even more elaborate applications powered by JavaScript.
Kudos to Flickr for these great articles, I hope they keep them coming!
