    OK, that's valid. But if your minimizer is an actual parser it could insert them again as necessary. Or just not remove the linebreaks, => you keep the linebreaks, lose the semicolons, they're roughly the same number so there's nothing lost. Commented Aug 7, 2011 at 13:55

    @Einar Egilsson Closure Compiler indeed does this. Commented Aug 7, 2011 at 15:42

    All things being equal, a newline is the same number of bytes as a semicolon. Your minimizer may strip all new lines, but then requires there to be semicolons. It's an even exchange. Commented Aug 7, 2011 at 17:19

    @Logan: That's assuming one byte newlines, of course ;-) Commented Aug 7, 2011 at 17:36

    Of course, if we used Python instead of Javascript, we'd have to code WAY less to do the same thing, so the fact that semi-colons use a few bytes less than indentation is a moot point. Commented Aug 8, 2011 at 7:11
