I use it for in component logic in vue. Used to have a collection of boolean or enum variables that represent the state of the component and change according to actions e.g. const isLoadingUser = ref(true). This works but often leads to unforeseen states being possible and just isn't very clear. In contrast, with xstate you define all states and legal transitions and wire everything up to send events, you can write guards that prevent transitions. I transitioned all my complicated multi stage forms to xstate and since doing so they've become substantially more robust. I highly recommend trying to out.
