 A call to `promisify(f)` returns a wrapper around `f` `(*)`. That wrapper returns a promise and forwards the call to the original `f`, tracking the result in the custom callback `(**)`.
 
-Here, `promisiefy` assumes that the original function expects a callback with exactly two arguments `(err, result)`. That's what we encounter most often. Then our custom callback is in exactly the right format, and `promisify` works great for such a case.
