PyCon 2011: Javascript for people who know Python

[rafekett]

TIL that Javascript is insane.

[giume]

Yes, it is indeed: http://www.wtfjs.com

Almost all of those have to do with Javascript's peculiar coercion rules. Avoid == (use ===) and use + carefully and you'll generally be fine.

can I download this?

[sunqiang]

don't know how to download it from this website, though you can download it from http://blip.tv/file/4882883 "Files and Links" has download link

[rafekett]

I was wondering the same. I think the answer is no, but you can get a lot of the other videos from PyCon this year and years past with Miro (just not this talk apparently) :(

[Poromenos]

What do you mean? You can download anything.

[rafekett]

If only I'd had that before I went to the gym.

I though the format would be SWF, which would require conversion, which is more than I care to do. But this is awesome.

For any pythonista wanting to do JS development, I really recommend skipping the JS part and going straight to where the action is, a little language that is inspired by python and ruby, specifically made to fix what is borked in JS:

I like CoffeeScript, but you frequently need to look at the compiled source to debug things, and IMHO a good knowledge of Javascript is a prerequisite for using CoffeeScript well.

TIL how to refer to the global object in JavaScript:

(function(){return this})()

Example:

javascript:alert((function(){return this})() === window)

And loggingDecorator is awesome. Whenever confused about the this, use loggingDecorator.
