summary
Argues that the Actor Model makes reactive apps simpler by modeling components as independent actors that communicate by messages, using mailboxes to guarantee mailbox ensures one message at a time and a guardian-root hierarchy for location transparency and fault tolerance. Shows XState integration: XState v5 requires explicit actors and the ability to spawn order actors per order so each order has its own behavior. Announces xactor, a tiny implementation at 1.5 kilobytes minified gzip.
