[React] Extracting Private React Components

we leverage private components to break our render function into more manageable pieces without leaking the implementation details of our component.

<!DOCTYPE html>

<head>
  <meta charset="utf-8">
  <title>JS Bin</title>
  <script src="//fb.me/react-0.14.3.js"></script>
  <script src="//fb.me/react-dom-0.14.3.js"></script>
</head>
<body>
  <div id="app"></div>

</html>

const users = [
  { name: 'Merrick', id: 1 },
  { name: 'John', id: 2 },
  { name: 'Trevor', id: 3 }
]


const UserListItem = ({user}) => {
  return (
     <div>
       {user.name}
     </div>
  );
};

class UserList extends React.Component {
  render(){
    return (
      <div>
        <h1>Users</h1>
        {
           this.props.users.map( (user) => {
              return <UserListItem user={user} key={user.id} />
           })
        }
      </div>
    );
  }
}

ReactDOM.render(<UserList users={users} />, document.getElementById('app'));
