Dear andrea molinari,

I believe the answer you have provided is not working because $("li:hidden") returns an array of elements, not a single item. Under the hood, it runs a loop and returns all the elements with the hidden pseudo selector. And the .show() method then goes through each of those returned items and makes them visible. That's the reason You can't store it in a const. I'm providing the solution below.

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

//happy Learning.
