You can't loop prompt and print like shown in the video.

I don't think my code is wrong because in the loop the function needs to print to the page before asking for another prompt but in the video browser writes to the page after each prompt. What is wrong ?

function capFirstLetter(str) {
  str = (str[0]).toUpperCase() + str.substr(1);
  return str
}


function stuSearch(aray, str) {

  var html = "";
  for (var obj in aray) {
    if ( str.toUpperCase() == (aray[obj].name).toUpperCase()) {
      for ( var prop in aray[obj]) {
        if ( prop == "name") {
        html += "<p><strong>" + capFirstLetter(prop) + ": "+(aray[obj])[prop] + "</strong></p>";
        } else {
        html += "<p>" + capFirstLetter(prop) + ": "+(aray[obj])[prop] + "</p>";
        }
      }
    }
  }
  print(html);
}

do {
  str = prompt("Enter student name");
  stuSearch(students, str);
}while(str != "quit")

You are correct. The behavior shown in the video is no longer possible while using a modern browser. There is a note about that fact in the Teacher's Notes of the video:

Important Update

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.

So this is not caused by a fault in your code.

You still can have it the same like in the video, and that by using Firefox browser. I noticed that when I was using Google Chrome then I tried with Mozilla Firefox. The Google Chrome didn't print it right away, but the Mozilla Firefox did! So, you may use Firefox for exact same experience ;)

best wishes.
