Any reason not to do my code like this? It has the same end result as the code shown in the video.

var name;
var track;
var achievements;
var points;

for (var i = 0; i < students.length; i += 1) {
  document.write("<h2>Student: " + students[i].name + "</h2>");
  document.write("<p>Track: " + students[i].track + "</p>");
  document.write("<p>Achievements: " + students[i].achievements + "</p>");
  document.write("<p>Points: " + students[i].points + "</p>");
};

Hi Ashton,

Can you provide a link to the video. I can't give you an answer without reference. However there is nothing wrong with your loop.

The bigger a program is, the more ways there are to accomplish the same thing.

Your code seems efficient and is easy to read. Without seeing the original, I can only guess this likely just as good as what is shown in the video.

If you leave a link to the course page I'll take another look.

It's fine but it's considered bad practice by many programmers, as it only works while the page is loading. If you call it after the page is done loading, it will overwrite the whole page. Also impossible to manipulate, We cannot go back to manipulate it without tapping into the DOM.

Use of document.write is in many of the video examples in the beginner courses. I'd guess that part is the same as the video until I see it.
