None.

The value of this, which is the async iterator object itself.

Note that you seldom need to call this method directly. The existence of the @@asyncIterator method makes all built-in async iterators async iterable, and iterating syntaxes like the for await...of loop automatically calls this method to obtain the async iterator to loop over.

const asyncIterator = (async function* () {
  yield 1;
  yield 2;
  yield 3;
})();
(async () => {
  for await (const value of asyncIterator) {
    console.log(value);
  }
})();
// Logs: 1, 2, 3
