Hi Error: no i defined,

Any idea to crack it?

app.js 
var section = document.querySelector('section');
var 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; 2019</p> 
        </footer>
        <script src="app.js"></script>
    </body>
</html>

Hey jc laurent,

The only thing you are missing is let keyword inside a for loop parentheses. 

for(let i = 0; i<paragraphs.length; i++) {
  paragraphs[i].style.color = "blue";
}

Hope this helps!
