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...
Memoization is an optimization technique used to accelerate applications. This blog guides users in implementing memoization in React applications.
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,...
ReactJS is a JavaScript library for building user interfaces with features such as JSX, and virtual DOM for efficient updates and unidirectional data flow.
