Just a quick question, why are you comparing against the string
'undefined', undefined is its own type and can be explicity tested
against, this saves casting it from one type to another. The same for
the if statement, doing an explicit match === for float detection, it
cant be anything other than

It's good, if it *were* CSS3's definition of empty. CSS3 def of empty

Hi all,
I find myself writing code like that the whole time:
example = example === undefined ? null : example;
We could imagine the following utility function:
$default = function(value, default) {
return value === undefined ? default : value;
}
So that the above could be sh
Gentlemen, based on your progress I've managed to implement some more
stuff. I've updated patch #7568.
Supported are nearly all of the argumentless pseudoclasses, which I
consolidated into one regex. (Also implemented the general sibling
combinator: "div ~ p".) I haven't done exhaustive testing

The purpose of JS2 is to open the way for more classical OO trained
programmers to use javascript, javascript is such a break from the
'norm' that its difficult for people who are expecting classes to
create elegant and maintainable code.
The hope is to maintain the prototypal abilties of javascr

It's really not as bleak as all that. Most of what JS2 borrows from
Java is syntax. And if you don't care for type annot

Prototype.js is not making Ruby in JavaScript. It just embraces the
conventions (modules, names, return types) because the two languages have
similar dynamic features. As for

Why cant prototype have elegant code and optimised code. I'm not
talking about milliseconds of optimisation, even i am not that
machocistic.
But when a function gets so much use like setStyle, should
asthetically pleasing code give way to optimisations to save seconds
or even minutes.

The main problem is with the use of name.camelize() in the final call

Without the camelization of the name everything works must faster.
I personally always camelize the values in the object i pass to
setStyle before hand, instead of having the key as a string.
