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 ); })() ); ``` # --seed-- ## --after-user-code-- ```jsx ReactDOM.render(, document.getElementById('root')) ``` ## --seed-contents-- ```jsx class ReturnTempPassword extends React.Component { constructor(props) { super(props); } render() { return (
{ /* Change code below this line */ }
