What is the difference between `super()` and `super(props)` in React using ES6 classes?

When you want to access this.props in constructor() then you should pass props to super() method.

Using super(props):

class MyComponent extends React.Component {
constructor(props) {
super(props);
console.log(this.props); // { name: 'John', ... }
}
}

Using super():

class MyComponent extends React.Component {
constructor(props) {
super();
console.log(this.props); // undefined
}
}

Outside constructor() both will display same value for this.props.
