Well, that is a beautiful typo! I'll bet John Resig would be willing to agree that avoiding this group is avoiding insanity. :-) -- Scott

I haven't decided what I want to do with them yet. They are optional, of course.

You know he didn't expect anyone to notice. That's complete bullshit. I hadn't done anything to that page in years until you started focusing on it. I don't even consider it a particularly compelling test as running queries over and over is not standard practice for an application. You misconstrued that my comments about speed were strictly related to SlickSpeed. And again, testing QSA vs. QSA is ridiculous. They are all _fast enough_ with QSA. Of course, many browsers in use today cannot handle QSA, so the "slow lanes" are more important comparisons. > > When I post some results he responds by saying that I'm testing the > wrong thing. You were. Testing QSA vs. a library is stupid. Others have mentioned that too. ;) > Either the browsers are too recent or the computer is > too fast. It's nonsense, of course. I never said anything like that, except in reference to being "fast enough" in brand new PC's, which is not exactly a badge of honor. What about the millions of users who do not buy new PC's every six months? There's lots of them out there.

For years, these efforts have promoted themselves as "fixing Javascript" and that they "smooth out" cross- browser quirks. In reality, it's all been a fraud (or delusion) on their parts. My Library (and the CWR project before it) came about after it was determined that these scripts were not solving anything, but rather "punting" on everything (e.g. sniffing the UA string to make it look like their designs were realized). Then there is the outrageous "test-driven" development (as referenced by one of Resig's posts a couple of years back). What it translates to is a bunch of people who have no idea how to go about cross-browser development, using unit tests to shape their designs. It's programming by observation, not understanding. They should solve the problems first (without consulting the baseless UA string), then use unit tests to confirm their solutions are viable in as many environments as possible. Using the "crystal ball" approach is folly and results in patchworks that are never really done.
