React follows a component-based architecture, where the UI is broken down into small, independent components. Each component can have its own state and lifecycle methods. React uses a virtual DOM to manage updates and optimize performance.
React also provides a declarative approach to building UI, where the developer only needs to specify what should be displayed and React takes care of the rest. This makes it easier to reason about the code and reduces the risk of bugs.
React can be used with other libraries and frameworks, such as Redux for state management and React Router for client-side routing. It can also be used to build mobile applications using React Native.
React has a large and active community, with many resources and tools available to help developers get started and improve their skills.
