| Note: this page is a great way to try React but it's not suitable for production. | |
| It slowly compiles JSX with Babel in the browser and uses a large development build of React. | |
| Read this section for a production-ready setup with JSX: | |
| http://reactjs.org/docs/add-react-to-a-website.html#add-jsx-to-a-project | |
| In a larger project, you can use an integrated toolchain that includes JSX instead: | |
| http://reactjs.org/docs/create-a-new-react-app.html | |
| You can also use React without JSX, in which case you can remove Babel: | |
| https://reactjs.org/docs/react-without-jsx.html | |
