My reccomendation is that someone make a "translator" which can take some sensible language, and convert it into javascript.

done

Why java? That makes no sense at all. Shit, if I just write an applet I can at least "get the draw context as an image and draw pixels to it"

I mean, I know javascripts inconsistencies are bad...

Perhaps there is something I do not yet understand about this package...

There seems to be a whole mini-industry of compiling to Javascript. SML to Javascript, a list of some more languages

Huh, that second blog post seems very insightful...

1, yes. the 'implicit semicolon' is evil. probably brought to us by the crazy defacto standard way javascript was pulled out of thin air by some guys at netscape.
2. huh, i guess i've never wanted to do that.
3. i have been getting js and python mixed up lately, mostly wanting to do js things in python. js really makes it obvious that it is a scripting language where data structures are just syntactic sugar on hashes. python covers it up a little more, but I've beet writing python lately and craving the craziness of being able to access someinstance.member as someinstance['member'] (and there is python for this, someinstance.__get__('member') or so, but it's not as pretty)

Have you seen you can actually get an arbitrary raster area and draw to it from Javascript? Look up .

r_transpose_p July 20 2009, 04:50:25 UTC

whoa shit!

Thanks!

As far as silly DOM-shuffling graphics and animation effects, everyone is using pre-rolled libraries for that, because doing it from scratch and having it work well in every browser is just a whole lot of work. Yahoo UI, Jquery UI, script.aculo.us, the list goes on.

I find I use plain old Jquery, if not Jquery plus the UI module, in almost every real project I work on. It's pretty indispensable.

Bear in mind that Canvas doesn't really work in IE, including IE 8.

There's an extension to make that kinda-sorta happen, but it's ridiculously slow and only barely usable.

On the plus side, if you're using most browsers, canvas is totally awesome :-)
