I think this might be more effective if there was some kind of emphasis on lines which contain nothing but tokens used to end control structures, such as } or });

Frankly, as is, I think that javascript looks more crisp and sane than it really is (although, as another commenter points out, jQuery might not be the best choice for the current style norms).

Also, the Python choice, while a very cool project, is very atypical of Python style. I suggest using one of the more complex modules from Twisted.
