employee list doesn't show up

I re-typed the widget.js file from scratch, being careful to copy the code from the video exactly, and the employee list still doesn't show up.

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function () {
  if(xhr.readyState === 4) {
    var employees = JSON.parse(xhr.responseText);
    var statusHTML = '<ul class="bulleted">';
    for (var i=0; i<employees.length; i += 1) {
      if (employees[i].inoffice === true) {
        statusHTML += '<li class="in">';
      } else {
        statusHTML += '<li class="out">';
      }
      statusHTML += employees[i].name;
      statusHTML += '</li>';
    }
    statusHTML += '</ul>';
    document.getElementById('employeeList').innerHTML = statusHTML;
    console.log(statusHTML);
  }
};
xhr.open('GET', 'data/employees.json');
xhr.send();
console.log(statusHTML);

There are other files involved in the display. To facilitate analysis, make a snapshot of your workspace and post the link to it here.

The snapshot did the trick! It did not appear that the script code was ever being loaded, so I added this at line 27 of index.html (just before the line with "</body>"):

  <script src="js/widget.js"></script>

After that, it seems to be working well.

I keep getting an uncaught syntax error on the last line, does anyone know the reason? https://w.trhou.se/gjhoj5bfnx

It looks like your function is missing the final close brace (perhaps on line 18).

For future questions, always start a fresh question to give yourself the best chance of folks seeing and responding to it. I only saw that because I still had "follow" turned on from the last time I answered.

Please follow the advice I gave to Zoe and start a new question. Also, that's an unsharable direct URL to your workspace, it's temporary and only exists while you are using it. But you can use the snapshot function in the workspace and provide the link to that (not here, in the new question).

It looks like you already created a new question for this issue, but forgot to post the link to the snapshot there.

I left an answer on that question. Please delete these "answers" from this one.
