I've tried to DRY code, not really working

Hi. This is my code: for(var i = 0; i < students.length; i++) { document.write("<h1>" + "Student: "+ students[i].name + "</h1>"); document.write("<p>" + "track: " + students[i].track + "</p>"); document.write("<p>" + "achievement(s): " + students[i].achievement + "</p>"); document.write("<p>" + "point(s): " + students[i].points + "</p>"); }

I've tried to remove the: document.write and replace it with the function from the video. Didn't seem to work for me. Then i tried: var message = document.write. Didn't work either, why doesn't this work?

Fixed code formatting:

for(var i = 0; i < students.length; i++) { 
document.write("" + "Student: "+ students[i].name + ""); 
document.write("" + "track: " + students[i].track + ""); 
document.write("" + "achievement(s): " + students[i].achievement + "");
document.write("" + "point(s): " + students[i].points + ""); 
}

i think what your trying to do is as follows :

for ( i = 0; i < student.length; i++ ) {
    var message = "";
    message += '<h2>Student: ' + student[i].name + '</h2>';
    message += '<p>Track: ' + student[i].track + '</p>';
    message += '<p>Achievements: ' + student[i].achievements + '</p>';
    message += '<p>Points: ' + student[i].points + '</p>';

        // next line can be swapped with a function call to print instead
    document.write(message);
}
