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         


        

Answer 1

super() is used to call the parent constructor.

super(props) would pass props to the parent constructor.

From your example, super(props) would call the React.Component constructor passing in props as the argument.
