    super(props);
    this.state = {
      items: [],
      isLoaded: false,
    };

  componentDidMount() {
    fetch('https://jsonplaceholder.typicode.com/posts')
      .then(res => res.json())
      .then(result => {
        this.setState({
          isLoaded: true,
          items: result
        });
      });
  }

  render() {
    const { items } = this.state;
    if (!isLoaded) {
      return <div>Loading ... </div>;
    } else {
      return (
        <ul>
          {items.map(item => (
            <li key={item.id}>
              <h3>{item.title}</h3>
              <p>{item.body}</p>
