Minor Changes

• 89f9c27c #1622 Thanks @davidkpiano! - Spawned/invoked actors and interpreters are now typed as extending ActorRef rather than Actor or Interpreter. This unification of types should make it more straightforward to provide actor types in React:

  import { ActorRef } from 'xstate';
  import { useActor } from '@xstate/react';
  
  const Child: React.FC<{ actorRef: ActorRef<SomeEvent, SomeEmitted> }> = ({
    actorRef
  }) => {
    // `state` is typed as `SomeEmitted`
    // `send` can be called with `SomeEvent` values
    const [state, send] = useActor(actorRef);
  
    // . ..
  };

  It's also easier to specify the type of a spawned/invoked machine with ActorRefFrom:

  import { createMachine, ActorRefFrom } from 'xstate';
  import { useActor } from '@xstate/react';
  
  const someMachine = createMachine<SomeContext, SomeEvent>({
    // ...
  });
  
  const Child: React.FC<{ someRef: ActorRefFrom<typeof someMachine> }> = ({
    someRef
  }) => {
    // `state` is typed as `State<SomeContext, SomeEvent>`
    // `send` can be called with `SomeEvent` values
    const [state, send] = useActor(someRef);
  
    // . ..
  };
