XState vs redux-thunk: What are the differences?

XState: State machines and statecharts for the modern web. It is a library for creating, interpreting, and executing finite state machines and statecharts. It's a really powerful package that can be used to manage state in React Apps; redux-thunk: Thunk middleware for Redux. Redux Thunk middleware allows you to write action creators that return a function instead of an action. The thunk can be used to delay the dispatch of an action, or to dispatch only if a certain condition is met. The inner function receives the store methods dispatch and getState as parameters.

XState and redux-thunk can be primarily classified as "State Management Library" tools.

redux-thunk is an open source tool with 15.2K GitHub stars and 854 GitHub forks. Here's a link to redux-thunk's open source repository on GitHub.
