Reactive State Machines and Statecharts
summary
Argues that state machines and statecharts make application behavior explicit, claiming they eliminate entire classes of bugs, generate integration tests automatically and produce live visualizations. Shows XState plus a visualizer wired into RxJS/Redux devtools, a drag‑and‑drop calendar demo implemented as nested states, and cites industrial use (Curiosity rover mission control for a multi‑billion dollar system with one deployment chance). Demonstrates transitions, guards, actions and whether recovery paths exist.
