Example useEffect cleanup function?

[stevenharderjr]

The map is initialized via useEffect, but there is no cleanup function in the example code. Am I missing something?

export const Map = ({ center, zoom, onLoad }) => {
  const ref = useRef()

  const callback = status => {
    if (status === Status.SUCCESS) {
      const map = new window.google.maps.Map(ref.current, {
        center,
        zoom,
      })
      onLoad && onLoad(map)
    }
  }

  return (
    <>
      <MapContainer ref={ref} />
      <Wrapper apiKey={googleMapsKey} callback={callback}></Wrapper>
    </>
  )
}
