Welcome to the world of Statecharts

An introduction to statecharts — a formalism for modeling complex system behavior as an extension of state machines. Covers what statecharts are, their benefits (decoupled behavior, lower bug counts, scalability, testability), drawbacks (learning curve, increased lines of code), and how to use them including the W3C SCXML standard. Also introduces executable statecharts, which serve as a single source of truth for both runtime behavior and visual diagrams.
