Rails - May 2010 - Can RoR handle AJAX Response by Static Javascript code?

So it looks like on RoR, when Ajax (using form_remote_tag) returns a
success code, Javascript is also returned to handle the visual effects.

using Fiddler, I do see the following response:

    try {
    Element.update("vote_score", "Score 58");
    $("vote_score").visualEffect("highlight");
    } catch (e) { alert(''RJS error:\n\n'' + e.toString());
alert(''Element.update(\"vote_score\", \"Score
58\");\n$(\"vote_score\").visualEffect(\"highlight\");'');
throw e }

Will there be situation where the code is quite big (like 1 or 2k) that
RJS can use some sort of static Javascript already loaded to handle the
effect?

Is there any other ways to use static Javascript already loaded with the
page?  Must it be just raw Javascript and use the Prototype''s Ajax
success response to call the static Javascript code, or can it be some
Rails mechanism related to RJS?

You can call any loaded Javascript function, including ones you''ve
coded
yourself, using page.call from an RJS template or render block.  Cody
Fauser''s "RJS Templates" PDF, available for $10 at
O''Reilly, is still the
best source on RJS IMHO.

HTH,
Bill

But why use RJS here, which tends to encourage poor-quality JavaScript 
programming?  Heck, why use Rails and Ajax at all?  If the JavaScript is 
static, just do the whole thing on the client side.
