why the code doesn't work with upper or lowercase

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>Points: ' + student.points + '</p>';
  report += '<p>Achievements: ' + student.achievements + '</p>';
  return report;
}

while (true) {
  search = prompt("search student records: Type a name [Jody] (or type 'quit' to end)");
  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);
    }      
  }
}
