Students for loops?

This is the closest I can understand, but this doesn't work.

var message= "";
var student;
var student2;
var students= [
  {
    name: "Ivan",
    track: "Front-End Development",
    achievements: "13 badges",
    points: 5163
  },
  {
    name: "Sara",
    track: "Back-End Development",
    achievements: "12 badges",
    points: 500
  },
  {
    name: "Mark",
    track: "Design",
    achievements: "11 badges",
    points: 300
  },
  {
    name: "John",
    track: "Business",
    achievements: "11 badges",
    points: 2001
  },
  {
    name: "Rob",
    track: "iOS",
    achievements: "10 badges",
    points: 100
  },
  {
    name: "Rob",
    track: "Markic",
    achievements: "113123 badges",
    points: 100133
  }
];



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

function getStudentReport(student){
  var report = "<h2>Student: " + student.name + "</h2>";
  report += "<h2>Track: " + student.track + "</h2>";
  report += "<h2>Points: " + student.points + "</h2>";
  report += "<h2>Achievements: " + student.achievements + "</h2>";
  return report;
}

while(true){
  var pr1 = prompt("Enter name or quit to close:");
  if (pr1 ===null || pr1 === "quit"){
    break;
  }
  for (var i = 0; i<students.length; i+=1){
    for (var j=0; j<students.length; j+=1){
    if (students[i].name === students[j].name ){
      message= getStudentReport(students[i]) + getStudentReport(students[j]);
      print(message);
    }else if (students[i].name ===pr1) {
      student= students[0];
      message=getStudentReport(student);
      print(message);
    }
  }

}
}

Can anyone explain me am I on good way?

Cheers

Hey Ivan, I came with this solution. It is basically the same code as the video except for the print, i move it outside the if, so every time it loops through the for loop it will print whatever it is in the message variable.

var message = '';
var student;
var studentName;

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) {
  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);
  }
}
