False, JS have to be interpreted and you have issue with document not being fully loaded. And CSS is easy to parse, faster to parse and "run" than JS. No, saying that JS is faster than CSS is just false.

CSS too, and even can be prerendered. And CSS works when JS is disabled.

That's not an argument at all because with the right tool its just like using a compiler. See "make" for example. Also you have to see how much you gain with the preprocessor, maybe loosing 0.01ms per "make" is worse it since you write code 1.2 times faster...

And do not highlight the obvious disadvantages.

You have NO idea what you're talking about.

>> JS have to be interpreted

Yeah, because the Bible, the Quaran and the Declaration of Independence say so ...
