The paragraphs turns blue with the code pasted below but for some reason the challenge doesn't pass. Anything wrong?

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

for (i = 0; i < paragraphs.length; i++) {
  let paragraph = paragraphs[i];
  paragraph.style.color = "blue";
}
app.js 
const section = document.querySelector('section');
let paragraphs = section.children;

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

Everything is perfect, the only thing you are missing is that you didn't declare the variable "i" in your loop (the for loop) and the program is trying to find an "i" variable that doesn't exist. So if you fix that everything should be fine.

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

}
