5. Repetition, Repetition
I’ll let the code speak for itself:

      x = sprite.x;
      y = sprite.y;
      css = {
        opacity: opacity,
        fontFamily: fontFamily
      };
      function(request) {
        body = request.body;
        status = request.status;
        // ...
      }

The CoffeeScript Way
Each snippet above becomes a one-liner, thanks to pattern-matching:

      {x, y} = sprite
      css = {opacity, fontFamily}
      ({body, status}) -> ...
