Student Record Challenge (my solution)

I just thought to share the code I wrote with the extra challenge of showing results if two or more students match the search query and a message if there is no match. Fun stuff :)

Comments are welcome! 

var rawHTML = "";
var arrayNames = [];

var students = [
  {name: 'Karolyne Mosby', track: 'Web Design', achievements: 41, points: 6642},

];

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

function searchAndAssign (object) {
var search = prompt('Enter a student name to search or quit to exit');
var student;
var names = [];

if(search.toLowerCase() === 'quit') {
  console.log('quit');
  return 'quit'
}

for (var i = 0; i < object.length; i++) {
  student = object[i];
    if(search === student.name) {
      console.log('true');
      arrayNames.push([student.name, student.track, student.achievements, student.points]);
    }
}

if(arrayNames.length <= 0) {
   return "empty"; 
} 

return "found";
}

function buildArray () {
for(var i = 0; i < arrayNames.length; i++) {
  for(var j = 0; j < arrayNames[i].length; j++) {
    if(j === 0) {
      rawHTML += '<h2>' + arrayNames[i][j] + '</h2>';    
      } else if (j >= 1) {
      rawHTML += '<p>' + arrayNames[i][j] + '</p>';  
      }
  }
} 
}

while(true) {
  var answer = searchAndAssign(students)  
  if (answer === 'found') {
    buildArray();
    print(rawHTML);
    break;
  }
  if(answer === 'empty') {
    print('<h2>Not Found</h2>');
  }
  if(answer === 'quit') {
    print('<h1>Goodbye!</h1>');
    break;
  }
}
