Hi. Will the code inside `async {}` block execute even if I didn't call `await` on it? Shouldn't it actually start executing when I call `await`? Or `await` is just that it awaits for the execution to finish and doesn't mean that it shouldn't execute without await? Just without `await` it becomes redundant and behaves like `launch` not paying attention to the return type)

Yes, by default the code inside `async` will start right away. There is an optional parameter you can pass to the `async` function if you want to change that, though.

`await` is just there so you can get the result (or exception, in case of failure). If you don't need a result, you're correct that you can just use `launch`.

It's likely that you don't, though: <https://github.com/Kotlin/kotlinx.coroutines/issues/4202> If you do, please let us know in the comments!
