Quick Answer
UI-heavy jQuery performance: use CSS transitions instead of jQuery animations (GPU-accelerated), virtualize long lists, use DocumentFragment for bulk DOM inserts, debounce scroll/resize/input handlers, batch DOM reads before writes, use class toggling instead of inline styles, avoid .show()/.hide() in loops (use classList toggle with CSS transitions).
Answer
Cache selectors and DOM elements. Use event delegation. Minimize expensive animations. Lazy load images/content to reduce initial load.
