:point_right: There are many different approaches that would all work.

But one reasonably simple one that comes to mind would be to establish a CSS class that causes the highlighting to appear, and then use the JavaScript setInterval function to sequentially set and remove the CSS class from the elements of your word list. One of the arguments to setInterval is the amount of time between changes, so that would control the speed of the movement.
