Explores JavaScript’s setTimeout as a simple yet powerful scheduler that defers execution without blocking, enabling smooth animations, async patterns, and server-side load balancing. Walks through a smooth-scrolling example, highlights creative uses like guided tours and effects, and shows how timing-based logic boosts performance, responsiveness, and scalability.
Master CSS transitions to create smooth, performant UI polish: define property, duration, timing-function, and optional delay; choose easing (linear, ease-in/out/in-out) or custom cubic-bezier curves; implement fades, color shifts, and transforms; and level up with chained transitions and start delays for richer, responsive interactions.
