# --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 `Welcome` component in the parent component `App`. Here, give `Welcome` a prop of `name` and assign it a value of a string. Within the child, `Welcome`, access the `name` prop within the `strong` tags.

# --hints--

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

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

The child of `App` should be the `Welcome` component.

```js
assert(
  (function () {
    const mockedComponent = Enzyme.mount(React.createElement(App));
    return (
      mockedComponent.children().childAt(0).name() === 'Welcome'
    );
  })()
);
```

The `Welcome` component should have a prop called `name`.

```js
assert(
  (function () {
    const mockedComponent = Enzyme.mount(React.createElement(App));
    return mockedComponent.find('Welcome').props().name;
  })()
);
```

The `Welcome` component should display the string you pass as the `name` prop within `strong` tags.

```js
assert(
  (function () {
    const mockedComponent = Enzyme.mount(React.createElement(App));
    return (
      mockedComponent.find('strong').text() ===
      mockedComponent.find('Welcome').props().name
    );
  })()
);
```

# --seed--

## --after-user-code--

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

## --seed-contents--

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

  }
  render() {
    return (
        <div>
            { /* Change code below this line */ }
            <Welcome />
            { /* Change code above this line */ }
        </div>
    );
  }
};

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

  }
  render() {
    return (
        <div>
          { /* Change code below this line */ }
          <p>Hello, <strong></strong>!</p>
          { /* Change code above this line */ }
        </div>
    );
  }
};
```

# --solutions--

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

  }
  render() {
    return (
        <div>
          { /* Change code below this line */ }
          <p>Hello, <strong>{this.props.name}</strong>!</p>
          { /* Change code above this line */ }
        </div>
    );
  }
};

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

  }
  render() {
    return (
        <div>
            { /* Change code below this line */ }
            <Welcome name="Quincy"/>
            { /* Change code above this line */ }
        </div>
    );
  }
};
