Code Not Working

Hi,

I'm not sure why this set of code does not run the same way as the following (which is the correct answer): 

for ( let i = 0; i < paragraphs.length; i += 1) {
  paragraphs[i].style.color = "blue";
}
app.js 
const section = document.querySelector('section');
let paragraphs = section.children;

for (let i = 0; i < paragraphs.length; i += 0) {
  let paragraph = paragraphs[i];
  paragraph.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>

For the second code i doesn't increment so you have an infinite loop.

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

has i += 0. it should be i += 1
