1,869 PointsMy script is only printing the search results after I quit the prompt and I can't see the difference between mine & his.
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> Achievements: ' + student.achievements + '</p>';
report += '<p> Points: ' + student.points + '</p>';
return report;
}
while(true) {
search = prompt("Enter a student name");
if (search === null || search.toLowerCase() === 'quit') {
break;
}
for (var i =0; i < students.length; i += 1) {
student = students[i];
if (student.name === search) {
message = getStudentReport(student);
print(message);
}
}
}

You can see this explanation posted in the "Teacher's Notes" section of the Useful Array Methods 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.
And actually, they don't just wait for a loop to finish, they wait for the entire script to finish before they update the screen.
