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


Hi Error: no i defined,

Any idea to crack it?

var section = document.querySelector('section');
var paragraphs = section.children;

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

  paragraphs[i].style.color = 'blue';
<!DOCTYPE html>
        <title>Child Traversal</title>
            <p>This is the first paragraph</p>
            <p>This is a slightly longer, second paragraph</p>
            <p>Shorter, last paragraph</p>
            <p>&copy; 2019</p> 
        <script src="app.js"></script>

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!
