   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.

Consuming functions can be registered (subscribed) using the methods .then and .catch. The most important, fundamental one is .then. The syntax is:
