> It was created to be an improvement over the Javascript situation

I see this repeated everywhere in this thread. async/await originated in C# not JS.

The C# implementation is clearly an attempt of putting type-safety over exactly the same implementation JS promises use. Done because MS wanted to port the same behavior.

I honestly can't tell if you're trolling.

- the C# implementation predates even Promises in JS, so it is not "the same implementation" and your implication that C# was inspired by JS as opposed to the other way around is false. More background: [0]

- Typescript works fine with the JS implementation so any differences aren't for type safety reasons, but largely because C# has a multithreaded event loop unlike JS

Also promises (or "futures" as they're called elsewhere) aren't unique to any language. They're used in lots of places that predate both C# and JS's use, for example the twisted framework in Python.

You're implying people went from writing C# to JS code willingly and not just wrote it but went on "improving" the ecosystem and I just don't believe there are people insane enough to do it willingly so "it was invented separately in both instances" is far more likely.
