React starter with 9 lines html
Save this code as index.html and open by your (modern) browser. <div id=root /> <script type=module> import React from 'https://dev.jspm.io/react@16' import ReactDOM from 'https://dev.jspm.io/react-dom@16' ReactDOM.render( React.createElement('h1', null, 'hello'), document.querySelector('#root') ) </script> Enjoy! How it works This is shorthand html file without <html>, <body> and so on. Just <div
