Broken loop or print ><

I can type in a name but the prompt keeps coming up without printing the students info onto the page until I type quit or hit cancel. Any thoughts on my terribly copied code?

var message = "";
var student;
var search;

function print(message) {
  var outputDiv = document.getElementById('output');
  outputDiv.innerHTML = message;

function getStudentReport(student) {
    var report = '<h2>Student: ' + student.name + '</h2>'
    report += '<p>Track: ' + student.track + '</p>'
    report += '<p>Achievments: ' + student.achievment + '</p>'
    report += '<p>Points: ' + student.points + '</p>'
    return report;

while (true) {
    search = prompt('Searsch student records: type a name [Jody] (or type "quit" to end)');
    if (search === null || search.toLowerCase() === 'quit'){
for (var i = 0; i < students.length; i += 1) {
  student = students[i];
    if (student.name === search) {
        message = getStudentReport(student);

That's actually normal. As you can see in the Teacher's Notes, it is due to an update in browser behaviour:

"Since this video was shot, the behavior of most browsers has changed, so you won't see the same thing as I demonstrate in the video. In the video, you'll see that my script is able to print out to the browser using document.write( ) while inside a loop.

Most browsers no longer do that: they wait until the loop finishes and then they print to the window. So, you'll see a blank page until you type quit in the prompt window — then you'll see all the output printed to the screen."

Nice one!

I knew I was missing something, I remember seeing something about that earlier but I tend to hyperfocus. Thank you a ton!
