Async Iteration

Process async data streams

Use for await...of to iterate over async data sources like streams or paginated APIs.

async function* generateIds() {
  yield await fetchId(1);
  yield await fetchId(2);
}

for await (const id of generateIds()) {
  console.log(id);
}

This processes data as it arrives, without loading everything at once.
