Why can't I use DOM to add element and class in this example?

As mentioned in the title, why can't I use DOM to add the 'ul' and 'li' elements to the page? Here is my code:

let xhr = new XMLHttpRequest(); xhr.onreadystatechange = function(){ if(xhr.readyState === 4){ let employees = JSON.parse(xhr.responseText); let statusHTML = document.createElement('ul'); statusHTML.className = 'bulleted'; let statusDiv = document.getElementById('employeeList'); statusDiv.appendChild(statusHTML);

for(let i = 0; i < employees.length; i++){
  let employee = document.createElement('li');
  employee.textContent = employees[i].name;
  if (employees[i].inoffice = false){
    employee.className = 'out';
  } else{
  employee.className = 'in';
} 
  statusHTML.appendChild(employee);

} }; xhr.open('GET', 'data/employees.json'); xhr.send();

At first glance, I notice that the conditional expression contains an assignment ("=") instead of a comparison ("==").

But if that's not be the whole issue, please post a snapshot and I'll take another look.
