A quick analogy


Asynchronous programming is a model of programming that focuses on coordinating different tasks in an application. Its goal is to ensure that the application finishes executing those tasks in the smallest amount of time possible. From this perspective, asynchronous programming is about switching from one task to another when it is appropriate to create overlapping between waiting and processing time, and from there, shorten the total time taken to finish the whole program.

To understand the underlying idea of asynchronous programming, let's consider a quick, real-life analogy. Imagine a scenario in which you are cooking a three-course meal that contains the following:

  • An appetizer that will take 2 minutes of preparation and 3 minutes of cooking/waiting
  • A main course that will take 5 minutes of preparation and 10 minutes of cooking/waiting
