I think they’re talking about the async/await syntax that’s common now in high level languages. Like, what’s the difference between that, or using actual threads? The only advantage I see is that it’s significantly easier/faster to use hence why it’s popular with languages like JS.
If you are waiting for IO, why would you block your current thread and not let it do something else? Async does not only exist in JS.
