I think that the semi-colon comment at the very end of the video is in reference to Twitter Bootstrap, and his public drubbing of Twitter's @fat, regarding missing semi-colons causing JSMin errors. Fat said, "nope - that's a bug in jsmin. Probably should let @douglascrockford know about it though. thanks!". Douglas said in response, "That is insanely stupid code. I am not going to dumb down JSMin for this case." The whole issue is here. Some great comments: https://github.com/twitter/bootstrap/issues/3057 https://github.com/twitter/bootstrap/issues/3057
