  constructor(props) {
    this.state = {
      message: ''
    this.handleEnter = this.handleEnter.bind(this);
    this.handleKeyPress = this.handleKeyPress.bind(this);
  // Change code below this line
  componentDidMount() {
  componentWillUnmount() {

  // Change code above this line
  handleEnter() {
    this.setState((state) => ({
      message: state.message + 'You pressed the enter key! '
  handleKeyPress(event) {
    if (event.keyCode === 13) {
  render() {
    return (
