   What is the difference between a fan and a promise in JavaScript?

   • That’s a “singer”. 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”. 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”.

   How to create a promise-based alternative?

   • Create a promise-based alternative. The function delay(ms) should return a promise. That promise should resolve after ms milliseconds, so that we can add .then to it, like this: Rewrite the showCircle function in the solution of the task Animated circle with callback so that it returns a promise instead of accepting a callback. The new usage:

   How to chain a promise in JavaScript?

   • To chain promises, we use the then method, which takes a callback function as its parameter. The callback function receives the resolved value of the previous promise as its argument. Inside the callback function, we can return a new promise to continue the chain. Here's an example that demonstrates promise chaining:

   What is a promise object?

   • A Promise object serves as a link between the executor (the “producing code” or “singer”) and the consuming functions (the “fans”), which will receive the result or error. Consuming functions can be registered (subscribed) using the methods .then and .catch. The most important, fundamental one is .then. The syntax is:
