i reading this article , came across this:

gmail engineer adam de boor surprised audience noting company's gmail service written entirely in javascript, , of code, around 443,000 lines worth, written hand.

assuming wasn't talking gwt, that's ton of javascript code. made me wonder how manage all.

some questions: use write all? (i'm guessing emacs or vim or similar)

what use package , test all? know of sprockets packaging up, there else?

what use debug? firebug nice , all, have beefs it...

google uses home-grown javascript compiler optimize hand written js code before sending client. see http://code.google.com/closure/compiler/
