I have done the extra challenge but I have a bug, I can't see why I have to type twice 'quit' to leave the program.

var message = [];
var student;
var searchBox;


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

 function getStudentReport(student){
     var report= '<h2> Student: ' + student.name + '</h2>';
      report += '<p> Track: ' + student.track + '</p>';
      report += '<p> Achievement: ' + student.achievement + '</p>';
      report += '<p> Points: ' + student.points + '</p>';  
     return report;
 }
  while(true){
          searchBox = prompt('Search for student or type quit to leave the prompt'); 
          if( searchBox.toLowerCase() === 'quit'){
          break
          }   

    for(var i =0; i< students.length; i++){
              student = students[i];
          if(student.name === searchBox){
           message.push(getStudentReport(student));
         }
          if (student.name !== searchBox){
         searchBox = prompt( searchBox +" is not a student, try again. Search for student or type quit to leave the prompt");
           break
         }else{
         print(message);
         }    
      }    
  }
