Selecting a list item in JavaScript

In previous lessons, we accessed the select tag to get or change the selected list item. It's not really necessary. After all, you can directly set the property selected of some option tag to true.

For example, let's make the list item with number two selected:

let select = document.querySelector('#select'); let option = select[2]; option.selected = true;

Given a dropdown list and a button. By clicking on the button, make selected the last item in the list.
