I recently discovered state charts via xstate in JS/React. A truly empowering experience. I was able to resolve spaghetti code that accounted for 75% of business logic (not all bad paths handled, or good ones either really) and “worked” 90% of the time (certain transitions in certain states not implemented) into a state machine that accounts for all cases and actually works. Without the state machine, complexity seemed to scale exponentially. With the state machine, complexity scales linearly.

Since then I’ve thought I’m not sure how I could adopt a UI system without a state charts implementation. Most user interactions aren’t that complicated, but some can be, and really do need to be resolved into state machines unless you are an expert spaghetti developer.

So, very glad to see this and hope to see more and more implementations.
