Quick Answer
Tooltips and popovers efficiently: use one shared tooltip element positioned dynamically, not one per trigger. On mouseenter, position and show the shared tooltip; on mouseleave, hide it. Use CSS transitions for show/hide (opacity, transform). Tippy.js does this efficiently out of the box. For many triggers, event delegation on the container avoids binding to each trigger element.
