I prefer using Vite to create React apps, as it offers better speed and flexibility than other tools.Run the following command in your terminal and then follow the subsequent instructions to set up a TypeScript-based React app with Vite:npm create vite@latest react-tabs...
You use createContext() to create a Context, which also creates a Provider and a Consumer, but you only need the Provider, which will allow any React element below it in the tree to use the Context. Creating Context DashboardWidget.context.js Copy import React, { useState, createContext...
