It really depends on the browser, and in some browsers on the method (e.g. Gecko currently has two separate codepaths for DOM calls, one of which is a lot faster than the other at the cost of not being able to handle all calls). And it might compare favorably with the cost of extracting things from the innards of a JS object.... Performance measurement is hard. :( Performance prediction even harder. -Boris
