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

Question

Learning React from the docs and came across this example:

class Square extends React.Component {
  constructor() {
    super();
    this.state = {
      val         


        

Answer 1

To use this keyword we should use the super keyword before it. Why? super is used to call the parent class's constructor.

Now why do we need to call the parent's constructor? The answer is to initialize the properties values which we are referring through this keyword.
