React useDebounce Hook

Difficulty: Easy

Debouncing a fast-changing value (a search input, a window resize, a slider) is one of the first React-specific utilities every project needs. This snippet shows the simplest one-state useDebounce hook, a leading-edge variant for instant first reactions, and a useDebouncedCallback variant that wraps a function instead of a value. Pick the shape that matches what your component actually needs.
