My solution for the extra challenges

function print(message) {
    var elementItem = document.getElementById('container');
    elementItem.innerHTML = message;
}

/*
* This function will print the objects found
* or a message for the ones not found
*/
function searchName(name) {
    var message = '';
    for (var i = 0; i < students.length; i++) {
        student = students[i];
        if (name === student.name) {
            message += '<h2>Student: '+ student.name +'</h2>';
            message += '<p>Track: '+ student.track +'</p>';
            message += '<p>Achievements: '+ student.achievements +'</p>';
            message += '<p>Points: '+ student.points +'</p>';
            print(message);
        }
    }
    if (message === '') {
        message = "No student name " + name + " was found";
        print(message);
    }
}

/*
* Main part of the script
* everything starts here
*/
while (1) {
    var input = prompt(
        "Search student records: type a name[Jody](or type 'quit' to end)"
    );
    if (input === null || input === '' || input.toLowerCase() === 'quit') {
        break;
    } else {
        searchName(input);
    }
}
