He uses some even stronger rhetoric:
Pretty strong language (and pretty tailor-made for getting a nice, heated discussion going in your comments).
On the other hand, if your needs are really, really modest, you might be able to get by with relying solely on 'helpers' or copy-pasted code from the how-to for some JS toolkit. Say you're a sys-admin who just wants a bit of drag-and-drop fanciness in your Web console app (and you don't care if it's unusably slow or maybe unreliable in some browsers) -- you might get by fine with stuff from the Scriptaculous effects library, or using whatever RJS helpers Rails offers for that.
I'll also cop to the fact that some of this suspicion comes from being a second-language speaker of Japanese. I'll never be a native speaker of course, but I'm pretty comfortable that most of the time what I'm saying is grammatically and idiomatically correct. Speaking another language gives you a bit of insight into how hard it really is to translate one theoretically equivalent thing into another.
Actually I'm sure these "helpers" probably work really well within a fairly narrow band of functionality. Just like those computerized translation devices our soldiers are carrying around Baghdad are really good at spitting out preset phrases like "put your hands in the air" or "stop where you are." But if they wanted to expand that dialog into a discussion of Arabic history or art, they'd be SOL.
