Minor Changes

• #4429 7bcc62cbc Thanks @davidkpiano! - The new enqueueActions(...) action creator can now be used to enqueue actions to be executed. This is a helpful alternative to the pure(...) and choose(...) action creators.

  const machine = createMachine({
    // ...
    entry: enqueueActions(({ context, event, enqueue, check }) => {
      // assign action
      enqueue.assign({
        count: context.count + 1
      });
  
      // Conditional actions (replaces choose(...))
      if (event.someOption) {
        enqueue.sendTo('someActor', { type: 'blah', thing: context.thing });
  
        // other actions
        enqueue('namedAction');
        // with params
        enqueue({ type: 'greet', params: { message: 'hello' } });
      } else {
        // inline
        enqueue(() => console.log('hello'));
  
        // even built-in actions
      }
  
      // Use check(...) to conditionally enqueue actions based on a guard
      if (check({ type: 'someGuard' })) {
        // ...
      }
  
      // no return
    })
  });
