| Summary: | Use element.classList if available to speed up class manipulation | ||
| Description: | Element.classList is a new API introduced in HTML5 for manipulating the classes of an element. The API is documented on https://developer.mozilla.org/en/DOM/element.classList. This API is implemented in Firefox 3.6 and WebKit is planning to implement it. YUI could detect if this property is available and use it in the YAHOO.util.Dom.{add,has,remove}Class functions. A speedup of up to 12 could be achieved with Firefox according to this benchmark: |

I'm wary of implementing from a draft spec, especially if the feature does not exist in any A-grade browsers.
Leaving open to consider for future inclusion.
