Here is my solution to Student Record (Extra). Any thoughts?

function print(message) {
    var outputDiv = document.getElementById("output");
    outputDiv.innerHTML = message;
}
function showStudent(studentName) {
  var nameIndex = [];
  for (var i = 0; i < students.length; i++) {
    if (studentName === students[i].name.toUpperCase()) {
      nameIndex.push(i);
    }
  }
  var message = "";
  if (nameIndex.length === 0) {
    message += "<h2>Student not found.</h2>"
  } else {
    for (var i = 0; i<nameIndex.length; i++) {
      message += "<h2>Student: " + students[nameIndex[i]].name + "</h2>"
      message += "<p>Tracks: " + students[nameIndex[i]].track + "</p>"
      message += "<p>Points: " + students[nameIndex[i]].points + "</p>"
      message += "<p>Achievements: " + students[nameIndex[i]].achievements + "</p>"

    }
  }
  print(message)  
}

while (true) {
  var userInput = prompt("Type the name of the student to search or quit to finish.")
  if (userInput === null || userInput.toUpperCase() === "QUIT") {
    break
  } else {
    showStudent(userInput.toUpperCase())
  }
}
