/**
Unwrap the return type of a function that returns a `Promise`.
There has been [discussion](https://github.com/microsoft/TypeScript/pull/35998) about implementing this type in TypeScript.
@example
```ts
import type {AsyncReturnType} from 'type-fest';
import {asyncFunction} from 'api';
// This type resolves to the unwrapped return type of `asyncFunction`.
type Value = AsyncReturnType<typeof asyncFunction>;
async function doSomething(value: Value) {}
asyncFunction().then(value => doSomething(value));
```
