title: Pass a Callback as Props

# Pass a Callback as Props

---
## Problem Explanation
- Add the `GetInput` component to the render method in MyApp, then pass it a prop called `inpu`t assigned to `inputValue` from MyApp's state. Also create a prop called `handleChange` and pass the input handler `handleChange` to it.
- Add `RenderInput` to the render method in MyApp, then create a prop called `input` and pass the `inputValue` from state to it.

## Hints

### Hint 1
`state` is a property of `Myapp` class, so use 'this.state' to get the object value

### Hint 2
To learn more about state and props, read [State and Lifecycle](https://reactjs.org/docs/state-and-lifecycle.html) and [Components and Props](https://reactjs.org/docs/components-and-props.html).
