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

Any idea to crack the child challenge

Can't 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>

It looks like 'i' hasn't been defined in the for loop you need use let before i. Also you want to the loop to check if i is less than paragraphs.length rather than less than or equal to .
