# --description--

The last several challenges covered the basic ways to pass props to child components. But what if the child component that you're passing a prop to is an ES6 class component, rather than a stateless functional component? The ES6 class component uses a slightly different convention to access props.

Anytime you refer to a class component within itself, you use the `this` keyword. To access props within a class component, you preface the code that you use to access it with `this`. For example, if an ES6 class component has a prop called `data`, you write `{this.props.data}` in JSX.

# --instructions--

Render an instance of the `ReturnTempPassword` component in the parent component `ResetPassword`. Here, give `ReturnTempPassword` a prop of `tempPassword` and assign it a value of a string that is at least 8 characters long. Within the child, `ReturnTempPassword`, access the `tempPassword` prop within the `strong` tags to make sure the user sees the temporary password.

# --hints--

The `ResetPassword` component should return a single `div` element.

```js
assert(
  (function () {
    const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
    return mockedComponent.children().type() === 'div';
  })()
);
```

The fourth child of `ResetPassword` should be the `ReturnTempPassword` component.

```js
assert(
  (function () {
    const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
    return (
      mockedComponent.children().childAt(3).name() === 'ReturnTempPassword'
    );
  })()
);
```

The `ReturnTempPassword` component should have a prop called `tempPassword`.

```js
assert(
  (function () {
    const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
    return mockedComponent.find('ReturnTempPassword').props().tempPassword;
  })()
);
```

The `tempPassword` prop of `ReturnTempPassword` should be equal to a string of at least `8` characters.

```js
assert(
  (function () {
    const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
    const temp = mockedComponent.find('ReturnTempPassword').props()
      .tempPassword;
    return typeof temp === 'string' && temp.length >= 8;
  })()
);
```

The `ReturnTempPassword` component should display the password you create as the `tempPassword` prop within `strong` tags.

```js
assert(
  (function () {
    const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
    return (
      mockedComponent.find('strong').text() ===
      mockedComponent.find('ReturnTempPassword').props().tempPassword
    );
  })()
);
```

## --after-user-code--

```jsx
ReactDOM.render(<ResetPassword />, document.getElementById('root'))
```

## --seed-contents--

```jsx
class ReturnTempPassword extends React.Component {
  constructor(props) {
    super(props);

  }
  render() {
    return (
        <div>
            { /* Change code below this line */ }
            <p>Your temporary password is: <strong></strong></p>
            { /* Change code above this line */ }
        </div>
    );
  }
};

class ResetPassword extends React.Component {
  constructor(props) {
    super(props);

  }
  render() {
    return (
        <div>
          <h2>Reset Password</h2>
          <h3>We've generated a new temporary password for you.</h3>
          <h3>Please reset this password from your account settings ASAP.</h3>
          { /* Change code below this line */ }

          { /* Change code above this line */ }
        </div>
    );
  }
};
```

  }
  render() {

          { /* Change code below this line */ }
          <ReturnTempPassword tempPassword="serrPbqrPnzc" />
          { /* Change code above this line */ }
        </div>
    );
  }
};
