## Description

React Easy State is a state management library for React that utilizes the observable store pattern to synchronize user interface components with application data. It employs ES6 proxies to wrap plain JavaScript objects, enabling the system to monitor data mutations and automatically trigger component re-renders whenever accessed properties are modified.

The library distinguishes itself through a transparent reactive system that eliminates the need for explicit data binding or boilerplate code. By tracking dependencies during the rendering process, it ensures that components only update when the specific data they consume changes. To maintain performance during complex state modifications, the library implements synchronous mutation batching, which groups multiple data changes into a single update cycle.

Beyond core state management, the tool supports the execution of reactive side effects, allowing functions to automatically re-run in response to changes in observable data. This capability ensures that external systems and interface elements remain synchronized with the underlying application state. The library is distributed as an installable package and provides a direct integration into the component lifecycle.
