JavaScript JavaScript and the DOM (Retiring) Traversing the DOM Child Traversal

I'm having an issue with this quiz. My code seems to be correct, though the quiz times out before it can grade it.

The code seems to be correct, but the quiz asks me to reload before it grades.

app.js 
const section = document.querySelector('section');
let paragraphs = section.children;

for (let i = 0; i < paragraphs.length; i += 0) {
    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>

The increment clause of the loop, "i += 0", does not change the loop variable value, so the loop never completes.
