Clicking on one of the list items makes them all disappear

I wrote the code as instructed in the video. The buttons work, but the list items disappear all at once if I click on one of them.

Have you changed the event listener parameter to 'click' instead of 'mouseover'?

Make sure in the taskList.addEventListener function that you change your if statement to look for the tagName button instead of LI, as below.

taskList.addEventListener("click", (event) => {
    if (event.target.tagName == "BUTTON") {
        let button = event.target;
        let li = button.parentNode;
        li.remove();
    }
});

I found that, if mouseover is the action type and you hover over the first item, each item moves up and triggers the event.

If you move your mouse around the list and start at the bottom, they will be deleted one at a time.
