const Item = React.createClass({
  propTypes: {
    item: PropTypes.string.isRequired
  },


  render() {
    return <li>{this.props.item}</li>;
  }
});


const List = React.createClass({
  propTypes: {
    items: PropTypes.arrayOf(PropTypes.string).isRequired
  },


  render() {
    const Items = this.props.items.map(item => <Item key={item} item={item} />);

    return <ul>{Items}</ul>;
  }
});


const fruits = [
  'apple',
  'orange',
  'banana',
  'kiwi',
  'pineapple',
  'golden kiwi',
  'green apple'
];


const fruitFilter = filter => fruit => fruit.toLowerCase().indexOf(filter.toLowerCase()) !== -1;


const App = React.createClass({
  getInitialState() {
    return {filter: ''};
  },


  render() {
    const filteredFruits = this.state.filter ?
      fruits.filter(fruitFilter(this.state.filter)) :
      fruits.slice(0);

    return (
      <div>
        <TextFilter onFilter={({target: {value: filter}}) => this.setState({filter})} />
        <List items={filteredFruits} />
      </div>
    );
  }
});

const appRoot = document.createElement('div');
document.body.appendChild(appRoot);
ReactDOM.render(<App />, appRoot);
