Is there a way to render multiple React components in the React.render() function?

Question

For example could I do:

import React from 'react';
import PanelA from './panelA.jsx';
import PanelB from './panelB.jsx';

React.render( 
  <PanelA />
  <PanelB />, 
  document.body  
);

where React would render:

body
   PanelA
   PanelB

Currently I'm getting the error:

Adjacent JSX elements must be wrapped in an enclosing tag

while transpiling with browserify and babelify

Since the React v16.0 release you can render an array of components without wrapping items in an extra element when you are inside a component:

render() {
  return [
    <li key="one">First item</li>,
    <li key="two">Second item</li>,
    <li key="three">Third item</li>,
    <li key="four">Fourth item</li>,
  ];
}

Remember only to set the keys.

UPDATE

Now from the 16.2 version you can use the Fragments

  render() {
    return (
      <React.Fragment>
        <td>Hello</td>
        <td>World</td>
      </React.Fragment>
    );
  }

Short syntax

  render() {
    return (
      <>
        <td>Hello</td>
        <td>World</td>
      </>
    );
  }

In the ReactDOM.render you still can't render multiple items because react needs a root. So you can render a single component inside the ReactDOM.render and render an array of items in the internal component.
