   Rendering a Nested Component in React.js

   • Create the app using npx create-react-app

     npx create-react-app quick-tips-react-children
     

   • Start the app

     npm start
     

   • Create the parent component using the children property

     import React from 'react';
     
     const ParentComponent = (props) => {
         return (
             <div>
                 <p>Parent component</p>
                 {props.children}
                 <p>After children content</p>
             </div>
         );
     };
     
     export default ParentComponent;
     

   • Use the parent component and nest some components inside it

     <ParentComponent>
         <a
             className="App-link"
             href="https://reactjs.org"
             target="_blank"
             rel="noopener noreferrer">
             Learn React
         </a>
     </ParentComponent>
