Asynchronous programming helps a user flow smoothly through an application. Let’s take a look at this programming practice with:

What is asynchronous programming?

It takes time for a function to fetch data from an API. Asynchronous programming was devised to accommodate for the lag between when a function is called to when the value of that function is returned.

Without asynchronous programming, apps would spend a long time on loading screens. A loading screen might appear:

  • When a user signs in, waiting for all their user data to be returned from the database.
  • During the user experience, waiting for the data to load at each new screen.

Asynchronous programming allows a user to go about his business in an application, while processes run in the background, thus enhancing the user experience.

Here’s an example: Data may take long a long time to submit to a database. With asynchronous programming, the user can move to another screen while the function continues to…
