Did you mean to say that some apps are not benefited by the fact that Javascript is single threaded instead? Having async functionality is not a bad thing since languages like Rust or Python have async funtionalities, but what they also have, is multi-threaded capabilities.
Exactly, multi-threading or parallel computing is the key when it comes to a lot of tasks. In fact, to take the full advantage of the 4 cores of your CPU, multi-threading is a must. Async will never be able to do that however efficient it may otherwise be.
It all comes down to what your app needs to do. I/O bound operations are where async shines and you should make full use of that if your app is majorly I/O bound.
