Trying to print out array of objects I get [object Objects]

So I seem to have terrible luck and spend more time fixing code then writing it haha. I'm following along with the video after making my own to see how he did it differently and i keep having this issue even though I've checked it over and over. When trying to print to the DOM all I get is [object Object]. Im going to print my code as is along with the src links for the js.

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Students</title> <link rel="stylesheet" href="css/styles.css"> </head> <body> <h1>Students</h1> <div id="output">

</div> <script src="js/students.js"></script> <script src="js/student_report.js"></script> </body> </html>

//student.js Array of Objects information var students = [ { name: 'Dave', track: 'Front End Development', achievements: 158, points: 14730}, { name: 'Jody', track: 'iOS Development with Swift', achievements: '175', points: '16375' }, { name: 'Jordan', track: 'PHP Development', achievements: '55', points: '2025' }, { name: 'John', track: 'Learn WordPress', achievements: '40', points: '1950' }, { name: 'Trish', track: 'Rails Development', achievements: '5', points: '350' } ];

//student_report.js prints out the list from inside the student array var message = ''; var student;

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

for (var i = 0; i < students.length; i += 1) { student = students[i]; message += '<h2>Student: ' + student.name + '</h2>'; }

print(student);

var students = [ 
  { 
   name: 'Dave',
    track: 'Front End Development',
    achievements: 158,
    points: 14730
  },
  {
    name: 'Jody',
    track: 'iOS Development with Swift',
    achievements: '175',
    points: '16375'
  },
  {
    name: 'Jordan',
    track: 'PHP Development',
    achievements: '55',
    points: '2025'
  },
  {
    name: 'John',
    track: 'Learn WordPress',
    achievements: '40',
    points: '1950'
  },
  {
    name: 'Trish',
    track: 'Rails Development',
    achievements: '5',
    points: '350'
  }
];

  var message = '';
  var student;

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

  for (var i = 0; i < students.length; i += 1) {
      student = students[i];
      message += '<h2>Student: ' + student.name + '</h2>';
  }

  print(student); //you are obviously printing an object, cause student is an object
//every time it runs through the loop, it would add one single object
//containing name, track, achievements, points per student 
//which is an object, code is doing right as expected
//should you be wanting to print(message)
