> the type of fetch() can't be inferred by static analysis
That is preposterous.
It's not. One might assume it's Node fetch, but parent post was just using a specific example to make a general point. Fetch can be `any`thing.
Would you say the same thing about
function getData() { return mysteryFunction(…); }
I feel like there are advantages to making it `async function`, even if it's superfluous, because it signals to readers and to static code analysis that the function returns a promise. That's assuming the return type of fetch(...) can't be inferred by static analysis and developer tooling.
