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

Help with traversing through child elements in Javascript

EDIT: So sorry all. Worked out the answer. I didn't declare 'i' as a var in the for loop. If someone answers I will mark as answered.

In part two of the final challenge in 'Javascript and the DOM' we are asked to color each paragraph within a parent blue.

I would have thought that the code I had written would work for this but it does not appear to be working. I would be very thankful if someone could enlighten me as to where I am going wrong.

Thanks!

app.js 
const section = document.querySelector("section");
let paragraphs = section.children;
for (i = 0; i < paragraphs.length; i++) {
  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>

Hi Ashton,

You found out right. Yes declaring the variable for i 'll work. :)
