JavaScript JavaScript Loops, Arrays and Objects Tracking Data Using Objects The Build an Object Challenge, Part 2

I need help with my code... How can I improve on my code?

My code runs but it only list the values in the array and not the name set for the values (like achievement, points , track and name). I usually find a way to get through the challenges, but I'm stuck on this one.

var students = [ { name: 'Najee Henderson', Track: 'Fullstack Development,JavaScript, Swift, ApI, Neural Networks', Achievements: 4, Points : 1348 }, { name: 'Anne Brickman', Track: ' Swift , Neural Networks', Achievements: 7, Points : 678 }, { name: 'Booty Brown', Track: 'Rapping', Achievements: 345, Points : 1 }, { name: 'Fat Lip', Track: ' ApI, Neural Networks', Achievements: 787, Points : 1348 }, { name: 'Albert Einstien', Track: 'Genius: Legend', Achievements: 40000, Points : "Infinity" }];

for( var n in students){

document.write('<h2>' + students[n].name + '</h2>') document.write( '<p>' + n,':', students[n].Track +'</p>') document.write( '<p>' + n,':', students[n].Achievements + '</p>') document.write( '<p>' + n,':', students[n].Points + '</p>')

}

Hello! You'll have to manually type those out and then put the code after the titles with the object values. And it makes the code a bit easier to read, if you make a separate function that prints the code out to the page.

I think it's easier to use a regular for loop in this case because it'll be easier to cycle through the array of objects Hope that helps! For example:

var html = " ";
for(var i = 0; i < students.length; i++) {
  html += "<h2>Student: " + students[i].name + "</h2>";
  html += "<p>Track: " + students[i].track + "</p>";
  html += "<p>Achievements: " + students[i].achievements + "</p>";
  html += "<p>Points: " + students[i].points + "</p>";
}

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