How would you return all other properties with the new given score???

[@AllThingsJavaScript]

Usually if you want something different returned you would pass in a different callback function. That is the nice thing about this pattern. You can accomplish different things. What exactly did you want returned?

Thank You... 👍👍👍

Awesome

[@oneein9183]

Not great. If you just name the function something like formatScore() and use it instead of callback(). It is so much more readable. I still didn't get it what is so special about callback except that it turns the code in spaghetti.
