When showing the output of running diff on Mac, Caroline accidentally showed the output of diff -u game_new.js game_old.js, that is, she put the files in the incorrect order. (She showed typing the correct command, but the output shown is from running the command with the arguments reversed). If you've run your command correctly, your output should be the reverse of Caroline's: that is, you should see minus signs where she has plus signs and vice versa.
