Hello I am creating the scoreboard app with React.

Everything works fine until I add the initial players.map arrow function step is implemented on line 52 (Players List comment). The scoreboard is supposed to show the name values under it using the player's array everything shows up when I inspect the element with dev tools until this step maybe it is something I am not catching watched the video 5x. https://teamtreehouse.com/library/iterating-and-rendering-with-map

const players = [ { name: "Guil", score: 50 }, { name: "Treasure", score: 85 }, { name: "Ashley", score: 95 }, { name: "James", score: 80 } ]; const Header = (props) => { return( <header> <h1>{props.title}</h1> <span className="stats">Player: {props.totalPlayers} </span> </header> ); }

const Player = (props) => { return( <div className="player"> <span className="player-name"> {props.name} </span> <Counter score={props.score} /> </div> ); }

const Counter = (props) => { return( <div className="counter"> <button className="counter-action decrement">-</button> <span className="counter-score">{props.score}</span> <button className="counter-action increment">+</button> </div> ); }

const App = (props) =>{ return( <div className="scoreboard"> <Header title="Scoreboard" totalPlayers={"1"}/>
// {Players List*/} {props.initialPlayers.map( player => <Player name={player.name} score={player.score} /> )}

      <Player name="Tyrique" score={20} /> 
      <Player name="Tyrique" score={30} /> 
      <Player name="Tyrique" score={10} /> 
      <Player name="Tyrique" score={15} /> 

      </div> ); }

ReactDOM.render( <App initialPlayers={players} />, document.getElementById('root') );
