  To the folks downvoting, the following is from Facebook's Front End Tech Talk: /** * Adding a single line to this file requires great internal reflection * and thought. You must ask yourself if your one line addition is so * important, so critical to the success of the company, that it warrants * a slowdown for every user on every page load. Adding a single letter * here could cost thousands of man hours around the world. * * That is all. */ http://www.slideshare.net/makinde/javascript-primer http://www.slideshare.net/makinde/javascript-primer Slide #47

      Thanks, did FB ever release anything more from Primer? https://gist.github.com/376039 https://gist.github.com/376039 Or is this it? I didn't see the comment.

        That it is, it just excludes the comment at the header. It has actually changed a bit since then, but that is still pretty much it.
