Upd - Advanced Hook

Enter . These are not just obscure APIs; they are architectural patterns and built-in tools ( useReducer , useCallback , useMemo , useRef , useLayoutEffect , useImperativeHandle , useDebugValue , and custom hooks) that, when mastered, transform your code from "working" to elegant, predictable, and highly performant .

This custom hook elegantly solves the "compare current vs previous" problem without extra state. Sometimes a parent component needs to call a child’s method (e.g., focus an input, reset a form, start an animation). While React discourages imperative code, advanced cases justify it. advanced hook

In the modern React ecosystem, hooks have revolutionized how we build components. Most developers are comfortable with the basics: useState for local state, useEffect for side effects, and useContext for dependency injection. But as applications grow in complexity, relying solely on these primitive hooks leads to tangled logic, performance bottlenecks, and hard-to-debug re-renders. Sometimes a parent component needs to call a
