Any reason not to use this function?

I got a working version of the function using the following method. Any reason something like this wouldn't be advised? It seems cleaner to me to have this as student_report.js

for (var i=0; i<students.length; i+=1) {
  document.write('<h2>The Student: ' + students[i].name + '</h2>');
  for( var key in students[i]) {
   if(key != 'name') {
     document.write('<p>', key, ': ', students[i][key], '</p>');
   }
  }
}

I can think of three potentially significant differences from the video solution:

  • you don't have control over the property display order with this method
  • you don't have the opportunity to show alternate key names (or capitalizations)
  • a missing property won't be shown at all (instead of shown as "undefined")

The importance of these differences might vary with the specific project and data set.
