Error with React render

I'm learning React/Redux from Wes Bos' tutorial. I'm trying to render some html, and there's an error building it every time:

    ERROR in ./client/reduxstagram.js
Module build failed: SyntaxError: /var/www/learn-redux/client/reduxstagram.js: Unexpected token (8:7)
  6 | import css from './styles/style.styl';
  7 | 
> 8 | render(<p>hi</p>, document.getElementById('root'));
    |        ^

    at Parser.pp.parseCallExpressionArguments (/var/www/learn-redux/node_modules/babylon/lib/parser/expression.js:348:20)

This is my reduxstagram.js file:

import React from 'react';

import { render } from 'react-dom';

// Import css
import css from './styles/style.styl';

render(<p>hi</p>, document.getElementById('root'));

Has anyone run into a similar problem, or know what I'm doing incorrectly?

I resolved with this configuratoin chunk for the javascript files:

// js
{
  test: /\.js$/,
  loader: 'babel',
  query: {
    presets: ['es2015', 'react']
  },
  include: path.join(__dirname, 'client')
}

You didn't setup webpack with the proper loaders to compile jsx, hence the Unexpected token. If you're new to webpack and javascript transpilers/compilers, start using something like jsbin and switch from Javascript to ES6 / Babel mode:

After you've got used to React and the jsx syntax, try learning how to setup webpack with babel.
