Yeah I also subscribe to Easy/Hard - Simple/Complex.

Async is simply multiplying by 2 for Complexity

If myResult = doMyThingWithMy(args) is a 1 then

const myPromise = askToDoMyThing(args);
const getMyResult = await myPromise;

Is a 2.

If you’re adding in error and flow control complexity, we’re simply arguing about how everyone cargo cults bullshit syntax and practices instead of using sensible things like a Maybe/Result monad where you have Result<success, value> and exceptions always crash.

Which is just multiplying complexity in these cases by 3. If Complexity is a logarithmic scale it’s just the next order. rather than the next next order.
