Quick Answer
Optimize jQuery event handling: use event delegation (single parent listener, not per-element), namespace events for clean removal, use .one() for handlers that fire once (auto-removes), throttle scroll/resize handlers, avoid re-binding events on DOM re-renders (use delegation instead), and profile with Chrome DevTools Event Listeners panel to find duplicate bindings.
Answer
Use event delegation for dynamic elements. Avoid attaching multiple handlers to the same element. Use namespaced events such as $(#el).on('click.namespace', handler) for better management. Improves memory usage and maintainability.
