syntax error: what's wrong in my code?

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.lenght, 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;
   }

};

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