What does calling super() in a React constructor do?

Learning React from the docs and came across this example:

class Square extends React.Component {
  constructor() {
    this.state = {
      value: null,

According to Mozilla, super allows you to use this in the constructor. Is there any other reason to use a stand alone super (I know super allows you to access parent class’s methods as well) but with React is there any other use case of just calling super() by itself?
