Forgive me for going a little off topic here but is it really true that JS was async-friendly from day 1? When I started using JS seriously 8 years ago, async code was horrible (callback hell, etc.) The web standards guys retrofitted native async way after the matter.
Doesn‘t this more or less mean "the only execution environment is event based, has a run loop outside of your control and calls your code whenever it wants" and "there is no busy sleep". So it was callback based from day one. Is that the same as async? I think it is?
