"with" is another misunderstood feature of JS, imho, you have to be truly a
junior to make mistakes with that (and we all did common mistakes when we
were junior, is there anybody that blamed the language rather than hisself?)
The only problem I can spot with "with" is not about developers but the YUI
compressor and machine parsers ... there is nothing wrong there. I wonder
which part is ambiguous for humans, if they know what they are doing ...
onload = function(){
with(document){
with(body){
with(appendChild(createElement("div")))
appendChild(createTextNode("hello"));
with(firstChild)
innerHTML += " world";
}
}
};
... and script size is preserved ...
BTW, I have already done all these conversations years ago when I become
certified AS2 developers being a pro with AS1 and Macromedia decided to
change ActionScript (ECMA262) 2 times in 3 years ... good stuff, except
Macromedia does not exist anymore indeed and lost a lot of money putting
effort for something never truly adopted by developers until somebody else
put even more money (Adobe)
I do not like breaking stuff, ES5 supposes to avoid problems they had with
ES4 but if this is the direction, and this will be 'cause we cannot do
anything except adapt ourself, I do not think it will bring any concrete
benefit for developers except, as I've already said, a lot of confusion
added in the already most confused programming language ever.
