React: How To Utilize Context API With Class And Functional Components.
Well, React official documentation says Contexts provide a way to route data through the component tree without having to manually propagate props at each level. Think about a scenario in which several separate components at various degrees of nested levels need to access the same data. Data must be sent as props to the component tree when using React so that any component that requires it may access it. Parent components can send data to nested child components in this way. They use many layers of components to transfer data from one piece to another. Props drilling is a challenge when data must be routed across numerous features because specific parts get the braces and then pass them on to their child components as props. Level 1 – Parent Component (App.js): import React, { Component } from "react"; import ReactDOM from "react-dom"; import UserProfile from "./UserProfile.js"; class App extends Component { constructor(props) { super(props); ...
