Does the statics object work with ES6 classes in React?

someComponent = React.createClass({
  statics: {
    someMethod: function () {
      // ..
    },
  },
});

class Component extends React.Component {
  static propTypes = {
    // ...
  };

  static someMethod() {
    // ...
  }
}

class Component extends React.Component {
  ....
}

Component.propTypes = {...}
Component.someMethod = function(){....}
