What's the difference between “super()” and “super(props)” in React when using es6 classes?

Question

When is it important to pass props to super(), and why?

class MyComponent extends React.Component {
  constructor(props) {
    supe

Here is the fiddle I've made:jsfiddle.net. It shows that props are assigned not in the constructor by default. As I understand they are assinged in the method React.createElement. Hence super(props) should be called only when the superclass's constructor manually assings props to this.props. If you just extend the React.Component calling super(props) will do nothing with props. Maybe It will be changed in the next versions of React.
