My Solution to "The Student Record Challenge."

Here's a snapshot of my solution: https://w.trhou.se/9ugs9i924e

Here is the relevant JavaScript:

var message = '';
var student;
var html = '';
var searchQuery = '';
var studentIndex = -1;

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

function getSearchPrompt() {
  return prompt('Type the name of the student whose record you would like to display or type "quit" to exit.');
}

function getStudentIndex(searchName){
    return students.findIndex(
      function test(element){
        return element.name === searchName;
      }
    );
}

function getStudentInfo(query){
  studentIndex = getStudentIndex(query);
  if ( studentIndex >= 0 ) {
    student = students[studentIndex];
    message += '<h2>Student: ' + student.name + '</h2>';
    message += '<p>Track: ' + student.track + '</p>';
    message += '<p>Points: ' + student.points + '</p>';
    message += '<p>Achievements: ' + student.achievements + '</p>'; 
    print(message);
    message = '';
  }
}

function getSearchQueries() {
  searchQuery = getSearchPrompt();
  if ( searchQuery.toLowerCase() !== 'quit' ) {
    getStudentInfo(searchQuery);
    getSearchQueries();
 }
}

getSearchQueries();
