React DevTools

React DevTools is a browser extension that helps developers build and debug applications made with React, a popular JavaScript library for creating user interfaces. It allows developers to inspect the components of their app, see how they change over time, and track the data they use. By providing insights into how the interface is structured and how it responds to user actions, React DevTools makes the development process easier and more efficient, ultimately leading to better and more responsive applications. It's a valuable tool for anyone looking to understand or improve React-based projects.
