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

by

Learning React from the docs and came across this example:

class Square extends React.Component {
  constructor() {
    super();
    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?
