An alternative to `fs.watch()` that returns an `AsyncIterator`
```js
const { watch } = require('fs/promises');
(async () => {
const ac = new AbortController();
const { signal } = ac;
setTimeout(() => ac.abort(), 10000);
const watcher = watch('file.txt', { signal });
for await (const { eventType, filename } of watcher) {
console.log(eventType, filename);
}
})()
```
