I recently created a complete tutorial where I build a Redux Toolkit-inspired state management library from scratch using React and JavaScript.

The goal is to understand how Redux-style state management works internally instead of only using the package.

In the tutorial, I implement:

• A custom createStore function
• Store Provider
• Reducers and actions
• Subscribers and listeners
• useSyncExternalStore
• useSelector and custom store hooks
• Redux DevTools integration
• createSlice
• combineReducers
• shallowEqual
• Thunk functionality
• Final testing and debugging

I would appreciate feedback from the community, especially on the library design, API structure, and any improvements that could make this project more reliable or easier to use.

Please note: this is an educational project designed to understand Redux and state management concepts internally. It is not intended to replace the official Redux Toolkit.
