My code works in my environment

I am selecting all the elements with the children selector and it works in my environment, but I can pass this quiz.

app.js 
const section = document.querySelector('section');
let paragraphs = section.children("p");
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; 2016</p> 
        </footer>
        <script src="app.js"></script>
    </body>
</html>

I'm surprised to hear this works, the environment must be something rather unusual. I would expect you to get an error like "TypeError: section.children is not a function".

It is, however, an ordinary property and should work fine without the argument and parentheses.

const section = document.querySelector('section'); console.log(section);

      let paragraphs = section.children("p");
      console.log(paragraphs);

console.logging paragraphs gives me an array of three ps

You mean three more in addition to the ones shown inside section from the first log?

Most peculiar! I take it your "environment" is not any standard browser. Perhaps it's "auto correcting" the code and just ignoring the parentheses and argument completely?

But the challenge wants to see it done correctly.
