Function unstable_useAsyncComputedValue

unstable_useAsyncComputedValue<T>(
alienAsyncComp: AsyncComputed<T>,
): T | undefined
Experimental
React hook to read from an async computed signal. The hook fetches the current value, subscribing to changes via useSyncExternalStore, and triggers a get() call to retrieve updated data. Maintains an internal state for the resolved value of the promise.
Type Parameters
- T
  The type of the computed value.
Parameters
- alienAsyncComp: AsyncComputed<T>
  The async computed signal to read.
Returns T | undefined
The resolved value (or undefined if not yet resolved).
Example
```
const asyncSignal = createAsyncComputed<number>(async function*() {
  const val = someSignal.get();
  yield Promise.resolve(someSignal); // track async dep
  return val * 2;
});

function AsyncDisplay() {
  const value = useAsyncComputedValue(asyncSignal);
  return <div>Value: {String(value)}</div>;
}
```
