)); | |
class App extends Component { | |

Click me to focus email | |
</button> | |
</div> | |
); | |
} | |
// `this.emailRef.current` points to the `input` component inside of EmailInput, | |
// because EmailInput is forwarding its ref via the `React.forwardRef` callback. | |
onClickButton() { | |
this.emailRef.current.focus(); | |
