</ul><p>All of the tasks will be completed when all of the elements are deleted from the list list. Now all of the tasks are located in the items collection, and its length is equal to the number of li elements in the list. If the tasks are deleted, then the collection length will be equal to 0. And then you can show the message.</p>

<p>For the moment, we do not need to find a message that there are no tasks in the markup and to try to show it. First, let’s make sure that the collection length is actually decreasing. In order to do this, create a function that will check the length (by the way, we have already added the function declaration to the code for you). We will call this function every time after we remove a task.</p>
