class App extends React.Component
    render()
        return <div>hello react Component</div>
    


export default App;

 

index.js

import React from \'react\'
import ReactDOM from \'react-dom\'
import App from \'./01-base/01-class组件\'

ReactDOM.render(
<App></App>,
document.getElementById(\'root\')
