On the final code challenge I'm not sure what I'm missing.

Here's my code

app.js 
const section = document.querySelector('section');
let paragraphs=section.children;
for(i=0;i<paragraphs.length;i+=1){
    paragraphs[i].style.color='blue';
}
index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>Child Traversal</title>
    </head>
    <body>
        <section>
            <p>This is the first paragraph</p>
            <p>This is a slightly longer, second paragraph</p>
            <p>Shorter, last paragraph</p>
        </section>
        <footer>
            <p>&copy; 2016</p> 
        </footer>
        <script src="app.js"></script>
    </body>
</html>

You haven’t initialised i, so you’re trying to use a variable that doesn’t exist. It needs to be let i = 0; or var i = 0;.
