Need Help Please...

Not sure why this isn't working. I tried multiple iterations/subtle-changes but still am receiving an error that 'i' is not defined. Appreciate any help. Thank you!

var section = document.querySelector('section');
var paragraphs = section.children;
for (i = 0; i < paragraphs.length; i += 1) {
   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>

Remove the parenthesis around the blue value and use quote marks, it is a string value.

i is not defined because you haven't declared it as a variable, therefore you want to use the keyword before i:

for (let i = 0; i < paragraphs.length; i += 1) {}
