Renders an uncontrolled range input element that uses a callback function to pass its value to the parent component.

- Set the `type` of the `<input>` element to `"range"` to create a slider.
- Use the `defaultValue` passed down from the parent as the uncontrolled input field's initial value.
- Use the `onChange` event to fire the `onValueChange` callback and send the new value to the parent.

```jsx
const Slider = ({
  min = 0,
  max = 100,
  defaultValue,
  onValueChange,
  ...rest
}) => {
  return (
    <input
      type="range"
      min={min}
      max={max}
      defaultValue={defaultValue}
      onChange={({ target: { value } }) => onValueChange(value)}
      {...rest}
    />
  );
};

ReactDOM.createRoot(document.getElementById('root')).render(
  <Slider onValueChange={val => console.log(val)} />
);
```
