阅读更多关于 How do the various Javascript optimization projects affect DOM performance?

问题 There's a lot of capital C, capital S computer science going into Javascript via the Tracemonkey, Squirrelfish, and V8 projects. Do any of these projects (or others) address the performance of DOM operations, or are they purely Javascript computation related? 回答1: The performance of pure DOM operations (getElementById/Tagname/Selector, nextChild, etc) are unaffected as they're already in pure C++. How the JS engine improvements will effect performance does depend to an extent on the

There's a lot of capital C, capital S computer science going into Javascript via the Tracemonkey, Squirrelfish, and V8 projects. Do any of these projects (or others) address the performance of DOM operations, or are they purely Javascript computation related? The performance of pure DOM operations (getElementById/Tagname/Selector, nextChild, etc) are unaffected as they're already in pure C++. How the JS engine improvements will effect performance does depend to an extent on the particular techniques used for the performance improvements, as well as the performance of the DOM->JS bridge.
