What am I doing wrong here?

I am selecting the list elements as the way I understand it from the video. I am unsure why I get the below AST node type error. Someone please look at my code and tell me what I am doing wrong. Thank you.

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

    <title>Document</title>
    <link rel="stylesheet" href="style.css" type="text/css" media="screen" title="no title" charset="utf-8">

    <h2>Star Trek Characters</h2>

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

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

Hey Alex,

Challenges and the instructions associated with them are very specific and need to be followed exactly. Here the instructions do not say to create a variable or store the value in one, so by doing so, you are confusing the code checker which will always result in a Bummer!.

I did not try your code, but I don't see why that wouldn't work... just not what the checker wants.

Keep Coding! :) :dizzy:

Thanks for clarifying. I did not take that into account.

So I can see from a previous post that the answer: $( "li:hidden" ).show(); will work.

How ever. I fail to see what is wrong with my original answer where I put the hidden list items into a variable and then just simply called that variable on the next line with the show method attached to it.

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

Any input would be appreciated.
