5,230 PointsHey guys! Not exactly sure what happened, but I can no longer preview any React.js code....
//Decompressing Application: A Header with Several Players
//Make a Header function
function Header(props) {
return (
<div className="header">
<h1>{props.title}</h1>
</div>
);
}
Header.propTypes = {
title: React.PropTypes.string.toRequired,
};
function Player(props) {
<div className="player">
<div className="player-name">{props.name}</div>
<div className="player-score">
<div className="counter">
<button className="counter-action decrement"> - </button>
<div className="counter-score">{props.score}</div>
<button className="counter-action increment"> + </button>
</div>
</div>
</div>
}
Player.propTypes = {
name: React.PropTypes.string.isRequired,
score: React.PropTypes.number.isRequired,
};
function Application(props) {
return (
//create a div element for our code
//add a class to the div element
<div className="scoreboard">
<Header title={props.title}/>
<div className="players">
<Player name="Emily Schoof" score={10}/>
<Player name="Melissa Cook" score={11}/>
</div>
</div>
);
}
Application.propTypes = {
title: React.PropTypes.string,
};
ReactDOM.render(<Application title="My Scoreboard"/>, document.getElementById('container'));

5,230 PointsWait, nevermind! I just figured it out: I forgot to add the return(); to my Player function. I'll keep this question up just in case it will helps others.
