The useContext hook in React is a powerful tool for simplifying context consumption in functional components. It provides a straightforward way to access context values without the need for a consumer component, streamlining code and improving readability. With useContext, you can manage global state,...
What is the useReducer Hook? React `useReducer()` hook is a powerful tool for managing states in a more structured and predictable manner. Reducer in React is particularly useful when dealing with complex state logic that involves multiple actions or when you need to pass state and action dispa...
The Context API is a built-in feature in React that allows you to manage and share global state across components without having to pass props down through multiple levels. This is useful when dealing with state that is needed by many components in the application. Example: importReact,{useCo...
log('Render: ', child) return ( {child}: {value} ) } export default React.memo(Child) Note: If the component has a useState, useReducer, or useContext Hook, the state or context will still trigger a rerender. To regulate the memo’s typical behavior, which shallowly compares complex...

ReactJS is a JavaScript library for building user interfaces with features such as JSX, and virtual DOM for efficient updates and unidirectional data flow.
With this "useContext" hook store context value to two variables ( value and setValue). 'value' will be used to display current value and 'setValue' will be used to change value. See the code below. //NestedChild.js file import React, { useContext } from 'react'; import { MyContext...

Hooks like useState, useEffect, and useContext simplify state management, side effects, and data sharing between components. React’s core principle is to re-render components only when their state changes, optimizing performance. The useState hook enables components to manage and update their state,...
