JavaScript JavaScript Loops, Arrays and Objects Tracking Data Using Objects The Student Record Search Challenge

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.

Thank You. It works now.
