Here is my code:
I am calling the function run() on the click of a button. run() will call the function main() from the source code of bundle.js. The console logs that the function main() is not defined. I even tried running it in the console itself with no success.

```

<script type="text/javascript" src="bundle.js"></script>

<script type="text/javascript">
  function run() {
    main(document.getElementById('playlistUrl').value)
  }
</script>

<input id="playlistUrl" placeholder="Enter a link...">
<button onclick="run()" id="go">Go!</button>

```

the function run() is defined, but not any funtion from bundle.js
