### Needs

- Parent components pass default value of state into children component

- state management is handled by the children component ( uncontrolled )

- **when some parts of state in parent component changes, the children component can be `reset`**

### key

- simply `key=`

> When a key changes, React will create a `new component instance` rather than **update** the existing one.

```javascript

class EmailInput extends Component {

  state = { email: this.props.defaultEmail };

  handleChange = event => {

    this.setState({ email: event.target.value });

  };

  render() {

    return ;

  }

}

;

```
