The Student Record Search Challenge

Hello. Could someone please explain me why is this wrong. And is there a way I could track what is happening in every step of a JavaScript code?

var message = '';
var student;

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

do {    
    var input = prompt ("Enter a name of a student or exit with quit.");
    input = input.toLowerCase();    

    for (var i = 0; i < students.length; i += 1) {
        student = students[i];

        if (student.name === input){    
        message = '<h2>Student: ' + student.name + '</h2>';
        message += '<p>Track: ' + student.track + '</p>';
        message += '<p>Points: ' + student.points + '</p>';
        message += '<p>Achievements: ' + student.achievements + '</p>';
        print (message);
        }
      }

} while (input !== "quit");

Thank you!

This code is missing the "students" object, but I notice that the input is being converted to lower case. This means it can only find a match if the names are also stored in lower case.

You could make the comparisons case-insensitive by converting the name as you compare it:

        if (student.name.toLowerCase() === input){

And step debugging is a feature found in the Development Tools built into many browsers.
