Comprehensive Guide to React Basics

React is a JavaScript library developed by Facebook for building user interfaces that uses components as building blocks. Components manage their own state and compose to build complex UIs. React employs a virtual DOM for improved performance and uses a declarative paradigm that makes applications easier to reason about while aiming for efficiency and flexibility. Key tools in React's ecosystem include React Router for navigation, Redux for state management, React Native for mobile apps, and Next.js for server-side rendering.
