i have these objects in an array:

var students = [ { name: 'Dave', track: 'Front End Development', achievements: 158, points: 14730 },

{ name: 'Jody', track: 'iOS Development with Swift', achievements: '175', points: '16375' },

{ name: 'John', track: 'Learn WordPress', achievements: '40', points: '1950' },

{ name: 'Trish', track: 'Rails Development', achievements: '5', points: '350' } ];

and when i run it to return the value. it did not work and when i checked it in the console, there was no error. Please let me know what i did wrong. here is another part of my work:

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(message); }
