Problem with sample program in Async Generators and Iterators article

In Plunker, following `Open in Sandbox` link, code provided under "An example of use (shows commit authors in console):" doesn't work (because it doesn't include `fetchCommits` function).

Console shows error:

(index):9 Uncaught (in promise) ReferenceError: fetchCommits is not defined

(index):9 Uncaught (in promise) ReferenceError: fetchCommits is not defined

    at (index):9

    at (index):18

Running the code directly from the `run` link in article also doesn't work. Gives error:

holder-2.2.min.js:10 Uncaught TypeError: Cannot read property 'appendChild' of undefined

    at Object.e.run (holder-2.2.min.js:10)

    at holder-2.2.min.js:10

    at XMLDocument.h (holder-2.2.min.js:10)

Code in question:

(async () => {


  let count = 0;

  for await (const commit of fetchCommits('javascript-tutorial/en.javascript.info')) {

    console.log(commit.author.login);

    if (++count == 100) { // let's stop at 100 commits

      break;

    }

  }

})();

Apri l’articolo Async Generators and Iterators e analizza lo snippet “An example of use” insieme ai relativi link Open in Sandbox e run. Riproduci gli errori segnalati, quindi aggiorna l’esempio o i samples collegati in modo che fetchCommits sia disponibile e il codice venga eseguito senza l’errore Holder.
