In Transferring Props guide, Manual Transfer section will lead an error

var FancyCheckbox = React.createClass({
  render: function() {
    var fancyClass = this.props.checked ? 'FancyChecked' : 'FancyUnchecked';
    return (
      <div className={fancyClass} onClick={this.props.onClick}>
        {this.props.children}
      </div>
    );
  }
});
React.render(
  <FancyCheckbox checked={true} onClick={console.log}>
    Hello world!
  </FancyCheckbox>,
  document.body
);

When click Hello world! will lead a Uncaught TypeError: Illegal invocation error

that's because console.log needs console as thisValue and isn't bound to it when you pass it like this.
pass console.log.bind(console) and you're good to go.
