multiple records with same name & record not found solution - would appreciate any feedback.

Hi,

Here are my solutions to the extra tasks. Took me a while to work out but got there in the end I think. Any feedback on the solution would be appreciated:

var students = [
  {name: 'Ben', track: 'IOS', achievements: 10, points: 100},
  {name: 'Vicky', track: 'JAVA', achievements: 10, points: 100},
  {name: 'Ben', track: 'CSS', achievements: 15, points: 150},
  {name: 'Dave', track: 'HTML', achievements: 20, points: 200},
  {name: 'Tim', track: 'Android', achievements: 50, points: 500}
];

var message = "";
var search;
var found;

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("Enter a name to search or type 'quit' to exit");
  found = false; //set found to false every time the prompt is called so previous true values do not change the result
  if (search === null || search.toUpperCase() === 'QUIT') {
    break;
  }       
    for (i = 0; i < students.length; i += 1) {
    student = students[i];
      if (search.toUpperCase() === student.name.toUpperCase()) {
        message += getStudentReport(student); //If more than one record with the same name will both be added to the message
        print(message);
        found = true; 
      }
    } 
    console.log(found); //used this to help me test
    if (!found) { //if not found alert will show
      alert('Sorry ' + search + ' not found, please try again');
    }
};

Thanks for posting, Ben. I was going down a different path, trying to add a for loop within the student/search if statement. Your solution is definitely simpler than what I was trying. Here is my final code:

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

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)'); 
      found = false;//assume student value entered is not found
  if (search === null || search.toLowerCase() === 'quit') {
   break; 
  } 
  for (var i = 0; i < students.length; i += 1) {
  student = students[i];
    if (student.name.toLowerCase() === search.toLowerCase()) {
    message += getStudentReport(student);
    print(message);
      found = true;
    } 
  }
  //if value is false alert user student is not found. 
  if(!found){
      alert('Student not found!');
   }

}
