Your code so far


class MyForm extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      input: '',
      submit: ''
    };
    this.handleChange = this.handleChange.bind(this);
    this.handleSubmit = this.handleSubmit.bind(this);
  }
  handleChange(event) {
    this.setState({
      input: event.target.value
    });
  }
  handleSubmit(event) {
  event.preventDefault();
  this.setState({
    input: '',
    submit: this.state.input
  });
}
  render() {
    return (
      <div>
        <form onSubmit={this.handleSubmit}>
          { /* change code below this line */ }
<input value={this.state.input} onChange={this.handleChange} />
          { /* change code above this line */ }
          <button type='submit'>Submit!</button>
        </form>
        { /* change code below this line */ }
<h1>{this.state.submit}</h1>
        { /* change code above this line */ }
      </div>
    );
  }
};
