Patterns for efficient DOM manipulation with vanilla JavaScript

DOM manipulation in vanilla JavaScript can be optimized using efficient techniques. Use querySelector and querySelectorAll with specific selectors for element selection. Implement event delegation to reduce event listeners, and apply debouncing and throttling for frequent events. Prefer textContent over innerText for text manipulation. When adding child elements, create and insert them directly rather than using innerHTML. Minimize reflows and prevent layout thrashing by grouping read and write operations separately. While these optimizations can enhance performance, their impact may be negligible in typical applications unless dealing with large-scale operations or animations.
