React Tracked: Manage state and prevent excessive re-rendering

State management in React has evolved significantly with tools like the React Context API and React Redux, but challenges remain in optimizing performance and preventing unnecessary component re-renders. This tutorial introduces React Tracked, a library that enhances application performance by using JavaScript proxies to track state changes and minimize re-renders. By comparing a vanilla React implementation with React Tracked, the tutorial demonstrates how the library reduces CPU usage by ensuring components only re-render when their specific state changes, rather than on every state update. This optimization is particularly beneficial in applications with large elements, where excessive re-rendering can lead to performance lags. The tutorial also contrasts React Tracked with Redux Selectors, highlighting React Tracked's ability to efficiently manage component re-renders through state tracking, ultimately improving application responsiveness and performance.
