Simplify proxy state with Valtio

State management in React can often be over-engineered, making the choice of a suitable library challenging for developers. Valtio is introduced as a new state-management library that simplifies proxy-state handling for JavaScript and React applications. Proxies, which are part of the Gang of Four design patterns, provide a way to control access and add functionality to objects, and Valtio leverages this concept to manage state data more efficiently without the need for large libraries. The library is developed by Poimandres, known for other popular React libraries, and allows developers to wrap state objects and mutate them throughout their applications. Valtio's useProxy hook ensures components only re-render when the relevant state changes, and subscribe functions allow developers to listen to specific state changes. The library can be used in both React and vanilla JavaScript applications, offering an easy setup and integration with a focus on simplicity and power.
