How can I fix this problem in my code?

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 a = 0;
var i = 0;
search = '';

while (search !== 'quit') {
search = prompt('which student are you looking for?');    

  for (i = 0; i < students.length; i+=1) {  

    if (search === students[i].name) {

      document.write('<h2>' + 'Student: ' + students[i].name + '</h2>');
      document.write('<p>' + students[i].track + '<p>')    
      document.write('<p>' + students[i].achievements + '<p>')    
      document.write('<p>' + students[i].points + '<p>')    

        }       
        }
  }
