 2. A "consuming code" that wants the result of the "producing code" once it's ready. Many functions  may need that result. These are the "fans".
 3. A *promise* is a special JavaScript object that links the "producing code" and the "consuming code" together. In terms of our analogy: this is the "subscription list". The "producing code" takes whatever time it needs to produce the promised result, and the "promise" makes that result available to all of the subscribed code when it's ready.
