>I just don't see the utility of pre-processors for JS or CSS. I'm not sure how CSS comes into the discussion, it isn't executed, and thus isn't debugged. And things like SASS and LESS are fairly simple, straightforward pre-processors. >I know I'm in the minority here, are developers really working without debugging? I don't think so. You couldn't pay me enough to write javascript. But I have to end up with some javascript because browsers don't support anything reasonable. So I use a haskell -> javascript compiler. I still have to read javascript to debug what is going wrong, but at least I don't have to write it.
