My solution to Dave's Extra Challenge (student search):

var message = '';
var student;
var request;
var multiStudents = [];

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>Points: ' + student.points +
        '</p>';
    report += '<p>Achievements: ' +
        student.achievements + '</p>';
    return report;
}

function noStudent(student) {
    var noreport =
        '<h2>Sorry, there is no student by that name of "' +
        student +
        '" in our recordes.</h2>';
    return noreport;
}

function multiple(count) {
    var multiName = (' We have ' +
        count +
        ' students in our recordes with that name:'
    );
    for (var i = 0; i < multiStudents.length; i +=
        1) {
        multiName += '<h2>Student: ' +
            multiStudents[i].name +
            '</h2>';
        multiName += '<p>Track: ' +
            multiStudents[i].track +
            '</p>';
        multiName += '<p>Points: ' +
            multiStudents[i].points +
            '</p>';
        multiName +=
            '<p>Achievements: ' +
            multiStudents[i].achievements +
            '</p>';
    }
    return multiName;
}
while (true) {
    request = prompt(
        'Search student recordes: type a name[Jody] (or type "quit" to end)'
    );
    var count = 0;
    var studentRecords = false;
    if (request === null || request.toLowerCase() ===
        'quit') {
        break;
    }
    for (var i = 0; i < students.length; i +=
        1) {
        student = students[i];
        if (student.name === request) {
            for (var j = 1; j <= 1; j +=
                1) {
                studName = students[j];
                if (student.name ===
                    studName.name) {
                    multiStudents.push(
                        student);
                    count += 1;
                }
            }
        }
    }
    if (count >= 1) {
        message = multiple(count);
        print(message);
        break;
    }
    for (var i = 0; i < students.length; i +=
        1) {
        student = students[i];
        if (student.name === request) {
            studentRecords = true;
            message = getStudentReport(
                student);
            print(message);
        }
    }
    if (studentRecords === false) {
        message = noStudent(request);
        print(message);
    }
}
