Next, change the color of each child paragraph blue.

Hi, I'm not sure where I'm going wrong with my code. I feel like its correct. I've looked at the other two answers for help but I keep getting an unexpected error that reads. Unexpected token < (3:17). could someone please take a look and give a hint. Thank you.

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

In the for loop conditions you need to separate them with

;

not

 ,

like this :

for(let i = 0; i < paragraphs.length; i += 1){
  paragraphs[i].style.color = 'blue'
};
