The video tutorial covers how to manipulate list items in the DOM using JavaScript. It starts with removing list items using the remove method and progresses to adding new items with innerHTML and event listeners. The tutorial highlights issues with event bubbling, explaining how new elements lack event listeners. It introduces append and prepend methods as alternatives to innerHTML for adding elements.
