There are three hidden items on this page-- a div and two list items. Use jQuery's :hidden pseudo selector to select only the hidden list items. Then use the show() method to expose the hidden elements.

You need to select all hidden list items then show them. You are currently just setting a variable to select all divs and all hidden list items

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

Unexpected AST node type passed to processExpressionStatement method: VariableDeclaration.

Why?

const $hidden = $(`ul`).find(`:hidden`)
$hidden.show();
