What do statecharts (XState) offer compared to a flat finite state machine?
- ✓Correct answer: Nested and parallel states without an explosion in their number
- 2Automatic generation of UI components from a state description
- 3Storing state on the server instead of the client
Explanation
A flat machine for a complex process (a video player, a multi-step form) grows quickly. Nested and parallel states, transition guards and side effects are described declaratively, and the diagram can be visualized and tested.
