Playing with ways to express immutable react elements with flowtype

ImmutableComponent.js

type FunctionComponent<P, S> = (props: P, context: S) => ?React$Element<any>;
type ClassComponent<D, P, S> = Class<React$Component<D, P, S>>;
type ReactComponent<D, P, S> = FunctionComponent<P, S> | ClassComponent<D, P, S>;

function ImmutableComponent<D, P, S, T: ReactComponent<D, P, S>>({ component: Component, componentProps }: {
  component: T,
  componentProps: P
}) {
  return <Component { ...componentProps }/>;
}
