React is an open-source JavaScript library developed by Facebook for building user interfaces. It uses a component-based development approach, allowing developers to easily build complex single-page applications (SPA).
React's core concepts are virtual DOM, component-based architecture, and one-way data flow. These features make React applications highly performant, maintainable, and scalable.
Break UI into independent, reusable components. Each component handles its own rendering and logic, improving code reusability and maintainability.
React achieves efficient UI updates through virtual DOM, only updating changed parts, reducing DOM operations and improving application performance.
JavaScript XML syntax allows writing HTML in JavaScript, making component structure clearer and development more efficient.
Data flows from parent components to child components, simplifying state management and making applications easier to understand and debug.
Provides rich lifecycle methods, allowing developers to perform specific operations at different stages of a component.
Feature introduced in React 16.8, allowing the use of state and other React features in functional components, simplifying component development.
