John Resig wrote an interesting piece on testing and its politics.
He poses a rather challenging question: how do we test real-world situations? Obviously that will depend on the applications themselves, but there are some things that I think are fairly global:
- Speed of loops. I've talked about this a long time ago, it's really easy to improve looping speed and brings about enormous performance boosts.
There are probably more things that can be done in terms of speed optimization on the web development front, and I think that server-side code is going to become more and more important in the speed optimization field (I'll leave that discussion for another time).
