Problem in variable declaration using jQuery :hidden pseudo

I have a problem error message as such when trying to show content using jQuery pseudo :hidden. It shows under Preview.

Challenge Task 1 of 1 CSS is being used to hide three items on the index.html page (two <li> elements and a <div> element). Use jQuery's :hidden pseudo selector and the show() method to display the hidden <li> elements, while leaving the <div> element hidden.

Bummer: Unexpected AST node type passed to processExpressionStatement method: VariableDeclaration

´´´ const $showItems = $('li:hidden'); $showItems.show();

index.html 
<!DOCTYPE html>
<html lang="en">
<head>
    <title>Document</title>
    <link rel="stylesheet" href="style.css" type="text/css" media="screen" title="no title" charset="utf-8">
</head>
<body>
    <h2>Star Trek Characters</h2>

    <ul class="character-list">
        <li>Captain Jean Luc Picard</li>
        <li>Data</li>
        <li>Worf</li>
        <li>Dr. Crusher</li>
    </ul>

    <div>I am supposed to stay hidden!</div>    

    <script
    src="jquery-3.2.1.min.js"></script>
    <script src="app.js"></script>
</body>
</html>
app.js 
const $showItems = $('li:hidden');
$showItems.show();

Your solution is technically viable, but the challenge is expecting to see a solution that uses function chaining and does not create an extra variable, like this:

$('li:hidden').show();

Given the rather cryptic error message that was produced and lack of more specific instructions, you may want to report this as a bug to the Support staff.
