Problem with sample program in Async Generators and Iterators article

Nobody has claimed this yet.

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;

    }

  }

})();

Open the Async Generators and Iterators article and inspect the “An example of use” snippet plus its Open in Sandbox and run links. Reproduce the reported errors, then update the example or linked samples so fetchCommits is available and the code runs without the Holder error.
