Which answer is correct?

Use `MutationObserver` to watch for new elements and attach handlers automatically.

— mutation_watcher

Re-attach event listeners after every DOM update.

— reattach_all

Use event delegation — attach ONE handler to the parent and check `e.target`: ``` list.addEventListener("click", (e) => { if (e.target.matches("li")) handleClick(e.target); }); ```

— delegate_it

Use jQuery's `.on()` with a selector: `$(list).on("click", "li", handler)`. This handles delegation automatically.
