| # --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
 | |
|     );
 | |
|   })()
 | |
| );
 | |
| ```
