What is Zustand and its core advantages?

Zustand is a lightweight React state management library designed based on hooks, providing a concise API for managing global state.

Core advantages:

1. Lightweight: Small size (about 1KB gzipped), no dependencies
2. Concise API: Create store with simple create function, no tedious configuration
3. No Provider needed: No need to wrap Provider component at the app top level
4. Hook-based: Fully compatible with React hooks, use useStore hook to access state
5. Middleware support: Built-in support for middleware like persist, devtools, etc.
6. Selective subscription: Can subscribe only to specific parts of state, reducing unnecessary re-renders
7. TypeScript friendly: Built-in TypeScript support with good type inference

Compared to Redux, Zustand reduces boilerplate code without concepts like action types or reducers; compared to Context API, Zustand offers better performance optimization and a more concise API.
