Someone has historical insights into why async/await seems to have taken over the world?
I often write Rust and I don't find it very attractive, but so many good projects seem to advertise it as a "killer feature". Diesel.rs doesn't have async, and they claim that perf improvement may not be worth it (https://users.rust-lang.org/t/why-use-diesel-when-its-not-as...).
For a single threaded JS program, async makes a lot of sense. I can't imagine any alternative pattern to get concurrency so cleanly.
