Is this as valid?

I used this code:

for (prop in students) {
    document.write('<h2> Name: ' + students[prop].name + '</h2>');
    document.write('<p> Track: ' + students[prop].track + '</p>');
    document.write('<p> Achievements: ' + students[prop].achievements + '</p>');
    document.write('<p> Points: ' + students[prop].points + '</p>');
}

And it produced the same result as Dave's code. I'm assuming that this isn't the right way to go about solving this problem?

Sameer,

the general rule of thumb is, use for loops to iterate through indices of arrays, and to use a for in loop to iterate through objects. In the example provided you are iterating though the properties of objects, a for in loop is perfect for that. My only issue with your code is using the document.write method. you should create a function that prints to the page by using either innerHTML or innerText.

There is never a wrong way to code something. Think of it more as best practice and logical. Does this code create something that is in accordance with best practices and works.
