Chapter 3. The Promise Paradigm

In this chapter, we will focus on what the promises paradigm is, from where it originated, how languages implement it, and what problems it can solve for us.

We have briefly discussed the origin of the promise pattern in Chapter 1, Promises.js. In this chapter, we will explore this subject in more detail, in a generic way, so that it would clear the logic and theory behind the adoption of promise in different languages and in particular, how it's helping us in today's modern programming.
