so far my solution, but is there a way that it doesn't matter if i write the name in capital or not.. 

var message = '';
var student;
var search;

var students = [ 
  {name: 'Lotte', track: 'JavaScript', achievements: '58', points: '1730'},
  {name: 'Damien', track: 'iOS', achievements: '175', points: '16375'},
  {name: 'Sandra', track: 'PHP Development', achievements: '155', points: '15025'},
  {name: 'Marc', track: 'Phyton', achievements: '40', points: '1950'},
  {name: 'Laureen', track: 'Css', achievements: '5', points: '350'}
];

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 the student records: type a name [Jody] (or type "quit" to end)');
  if (search === null || search.toLowerCase() === 'quit') {
    break;
  } else {
     print ( 'No student named ' + search + ' was found');
    }

for (var i = 0; i < students.length; i += 1) {
  student = students[i];
  if (student.name === search ){
    message = getStudentReport( student );
    print(message);
    }
  }
}

Hi Lotte, JavaScript is case-sensitive.

Hello Lotte,

Here is my solution. It prints only the records with same name and prints a message if there is no one with that name.

I hope it helps you.

var message = '';
var student;
var search;
var results = [];
var studentReport;

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

function getStudents(student) {
  studentReport = "<h2>Student: " + student.name + "</h2>";
  studentReport += "<p>Track: " + student.track + "</p>";
  studentReport += "<p>Achievements: " + student.achievements + "</p>";
  studentReport += "<p>Points: " + student.points + "</p>";
  return studentReport;
}
while (true) {
  search = prompt("Please type a name or type 'quit' to exit.");
  if (search === null || search.toLowerCase() === "quit") {
      break;
    }
  for (var i = 0; i < students.length; i++) {
    student = students[i];
    if (student.name.toLowerCase() === search.toLowerCase()) {
      results.push(getStudents(student));
      message = results.join("");
    }
    if (results.join("") === "") {
      message = "<br><h2>Sorry, no " + search.toUpperCase() + " listed here.</h2>";
    }
  }
  print(message);
  results = [];
}

Just change message= to message += so duplicate names will display ! while(true) { studentName = prompt("Whats the name of the student?"); if (studentName.toLowerCase() === 'quit' || studentName === null) { break; }

for (var i = 0; i < students.length; i += 1) { student = students[i]; if (studentName.toLowerCase() === student.name.toLowerCase()) { message += getStudentReport(student); print(message); }

}

}
