Before We Start

When you hear “asynchronous programming”, you might ask: what is it, and why should I care?

If you ask someone with experience, they’ll probably toss around terms like event loop, asyncio, or goroutines.
But in my view, asynchronous programming is just a nice way to organize the tasks you want your computer to do.

Let’s think back to how we used to program.
First, set a value. Then call some functions or run a loop. Finally, return 0 to the C runtime (or whatever).
It’s all sequential — we expect the code to do exactly what we wrote, top to bottom.
Sometimes we throw in threads for parallelism, but even then, we still expect each thread to run from start to finish, just like we wrote.
