JSX version of LikeButton

like_button.js

'use strict';

class LikeButton extends React.Component {
  constructor(props) {
    super(props);
    this.state = { liked: false };
  }

  render() {
    if (this.state.liked) {
      return 'You liked this.';
    }

    return (
      <button onClick={() => this.setState({ liked: true }) }>
        Like
      </button>
    );
  }
}

let domContainer = document.querySelector('#like_button_container');
ReactDOM.render(<LikeButton />, domContainer);

What changes would we have to make to the index.html file and the buttons we are making to use JSX?
