Component-Based Architecture: React applications are built using reusable components that manage their own state and can be composed together to create complex UIs.
Virtual DOM: React uses a Virtual DOM to efficiently update the real DOM. When a component’s state changes, React compares the new Virtual DOM with the previous one and updates only the changed parts of the actual DOM.
Declarative UI: React’s declarative approach lets you describe what the UI should look like based on the current state, and React handles updating the DOM to match this description.
Unidirectional Data Flow: Data flows in one direction from parent to child components via props, making it easier to manage and debug the application.
Event Handling and State Management: React handles events using synthetic events and manages component state internally or through external libraries like Redux or the Context API for complex applications.
