Direct text-based user input is a foundation for many apps. Writing a post or comment on a page is a canonical example of this. [`TextInput`](/react-native/docs/textinput.html#content) is a basic component that allows the user to enter text.
This example creates a simple `TextInput` box with the `string``Hello` as the placeholder when the `TextInput` is empty.
```JavaScript
import React from 'react';
import { AppRegistry, TextInput, View } from 'react-native';
