Small victory in JavaScript.

This is by no means impressive to anyone but me. However, I was able to add my first if/else statement to a bit of code. The code comes from the Accessing Object Properties video in the JavaScript Loops, Arrays, and Objects section.

The simple statement prints a message depending on whether the 'treehouseStudent' value is true or false. 

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Objects</title>
  <link rel="stylesheet" href="css/styles.css">
</head>
<body>
<h1>Objects</h1>
<div id="output">

</div>
<script src="js/object.js"></script>
</body>
</html>

var person = {
  name : 'Sarah',
  country : 'US',
  age : 35,
  treehouseStudent : true,
  skills : ['JavaScript', 'HTML', 'CSS']
};

function print(message) {
  var div = document.getElementById('output');
  div.innerHTML = message;
}

var message = '<p>Hello. My name is ' + person.name + '.</p>';
message += '<p>I live in the ' +person.country + '.</p>';
person.name = 'Rainbow Dash';
message += '<p>But, I wish my name was ' + person.name + '!</p>';
person.age += 1;
message += '<p>My age is now ' + person.age + '.</p>';
message += '<p>I have ' + person.skills.length + ' skills: ' ;
message += person.skills.join(', ') + '</p>';
if (person.treehouseStudent) {
  message += '<p>I am currently a student at Treehouse.</p>';
} else {
  message += '<p>I am not currently enrolled at Treehouse.</p>';
}

print(message);

EDIT: Typo
