Promises, Futures & Async Operations

Welcome! In this lesson, we'll explore asynchronous programming in Clojure. This is key for building responsive applications that don't freeze while waiting for long tasks.

Asynchronous tasks run in the 'background', allowing your main program to continue without interruption. When the background task finishes, it delivers its result.

Imagine fetching data from a slow server. A blocking operation would make your application wait until the data arrives. During this time, nothing else can happen.

A non-blocking operation starts the fetch but immediately returns control to your application. Your app can then do other things, and process the data once it's available.
