var students = [

    name: 'brooklyn',
    track: 'Front-end Web Developer',

  },

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

    counter = 0;  //set counter to 0 every time run the while loop.
    search  = prompt('input a student name, type quit to end.');
    if (search === null || search.toLowerCase() === 'quit'){
        break;
    } 
    for (var i = 0; i < students.length; i++ ) {
        student = students[i];
        if ( search.toLowerCase() === student.name.toLowerCase() ) {
            counter += 1;
