This article explains why overusing useState in complex React components can lead to tangled code and bugs, and demonstrates how switching to useReducer provides a single source of truth, clearer actions, and more maintainable state management.
This article explains React Hooks introduced in version 16.8, detailing the purpose and usage of common hooks such as useState, useEffect, useContext, useReducer, useRef, useCallback, and useMemo, and provides practical code examples for each.
This tutorial introduces React Query (TanStack Query), explains its motivation, demonstrates how to manage client and server state in React using hooks, Context, useReducer, and provides best practices for caching, optimistic updates, reducing duplicate requests, and performance optimization techniques.
This article provides in‑depth guidance on using React hooks such as useState, useEffect, useContext, useReducer, and related utilities, covering lazy initialization, functional updates, performance‑optimising patterns, state sharing strategies, and advanced techniques like useImmer and react‑tracked to reduce mental overhead and avoid bugs.
React’s useReducer hook, introduced in version 16.8, lets a component manage complex state by supplying a reducer function and an initial value, returning [state, dispatch] where dispatch triggers actions; it supports lazy initialization, centralizes updates, works with useContext for shared state, and is preferable to useState for non‑trivial logic but less suited than full Redux for large‑scale state needs.
This article explains how useReducer can replace useState for complex state logic, introduces Context for sharing data across components, demonstrates their combined usage with code examples, and compares this approach to React‑Redux, highlighting differences in data flow, rendering behavior, and suitable scenarios.
This article explores why React Hooks can display stale state values, comparing functional and class components, explaining closure behavior, dependency‑array mechanics, proper data‑fetching patterns, and when to replace useState with useReducer to avoid common pitfalls.
