React Base Fiddle (JSX)

Starting point for creating JSFiddles with React.

HTML

<script src="https://unpkg.com/react@16/umd/react.development.js"></script>
<script src="https://unpkg.com/react-dom@16/umd/react-dom.development.js"></script>
  <div id="todo-wrapper">
    <!-- React stuff goes here -->
  </div>

Babel + JSX

var TodoComponent = React.createClass({
    render: function(){
        return(
            <h1>Hellooooo</h1>
        );
    }
});

ReactDOM.render(<TodoComponent />, document.getElementById('todo-wrapper'));
