async function* gen() {

  yield 1;

  await Promise.resolve();

  yield "foo";

  await Promise.resolve();

  yield true;

}

const { port1, port2 } = new MessageChannel();

from(gen())

  .pipeThrough(switchMap((chunk) => [chunk, typeof chunk]))

  .pipeTo(postMessage(port1))

  .finally(() => port1.close());

const result: unknown[] = [];

await fromMessage(port2)

  .pipeThrough(take(6))

  .pipeTo(forEach((chunk) => {

    result.push(chunk);

  }))

assertEquals(result, [

  1,
