{"version":"1.0","type":"rich","title":"React crash course","description":"A React crash course demonstrates rendering a static \"Hello React!\" message through the component-based React API. The example uses React 16.13.1 and ReactDOM to mount an `App` component into a DOM element with `ReactDOM.render`. It imports hooks like `useState`, `useEffect`, `useRef`, and `useReducer`, though the current component does not invoke them. The index.html file defines a large text style and loads production builds of React and ReactDOM from unpkg.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c40e8944761b421986afc9320b963d93?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
