💕Add a file named index.js in the src/ folder with Js code.

          import React from 'react';

      import ReactDOM from 'react-dom';
      import './index.css';

      class Square extends React.Component {
  render() {
    return (
      <button className="square">
        {/* TODO */}
      </button>
    );
  }
}

class Board extends React.Component {
  renderSquare(i) {
    return <Square />;
  }

  render() {
    const status = 'Next player: X';

    return (
      <div>
        <div className="status">{status}</div>
        <div className="board-row">
          {this.renderSquare(0)}
          {this.renderSquare(1)}
          {this.renderSquare(2)}
        </div>
        <div className="board-row">
          {this.renderSquare(3)}
          {this.renderSquare(4)}
          {this.renderSquare(5)}
        </div>
        <div className="board-row">
          {this.renderSquare(6)}
          {this.renderSquare(7)}
          {this.renderSquare(8)}
        </div>
      </div>
    );
  }
}

class Game extends React.Component {
  render() {
    return (
      <div className="game">
        <div className="game-board">
          <Board />
        </div>
        <div className="game-info">
          <div>{/* status */}</div>
          <ol>{/* TODO */}</ol>
        </div>
      </div>
    );
  }
}



ReactDOM.render(
  <Game />,
  document.getElementById('root')
);


💕In particular, we have three components:

• Square
• Board
• Game

The Square component renders a single <button>, the Board renders 9 squares, and the Game component renders a board with some placeholders that we'll fill in later. None of the components are interactive at this point.

     
💕passing some data from the Board component to the Square component.

   class Square extends React.Component {
  render() {
    return (
      <button className="square">
        {this.props.value}
      </button>
    );
  }
}

class Board extends React.Component {
  renderSquare(i) {
    return <Square value={i} />;
  }

  render() {
    const status = 'Next player: X';

    return (
      <div>
        <div className="status">{status}</div>
        <div className="board-row">
          {this.renderSquare(0)}
          {this.renderSquare(1)}
          {this.renderSquare(2)}
        </div>
        <div className="board-row">
          {this.renderSquare(3)}
          {this.renderSquare(4)}
          {this.renderSquare(5)}
        </div>
        <div className="board-row">
          {this.renderSquare(6)}
          {this.renderSquare(7)}
          {this.renderSquare(8)}
        </div>
      </div>
    );
  }
}

class Game extends React.Component {
  render() {
    return (
      <div className="game">
        <div className="game-board">
          <Board />
        </div>
        <div className="game-info">
          <div>{/* status */}</div>
          <ol>{/* TODO */}</ol>
        </div>
      </div>
    );
  }
}


ReactDOM.render(
  <Game />,
  document.getElementById('root')
);
