Component-Based Architecture in React.js involves breaking down the user interface into reusable, self-contained components. These components encapsulate their logic and presentation, promoting code reusability, maintainability, and scalability in web applications, fostering a modular and organized development approach.
React uses a virtual representation of the DOM called the Virtual DOM. When data changes in a React application, it updates the Virtual DOM first, then calculates the difference between the current Virtual DOM and the previous one, and finally updates the actual DOM efficiently. This approach minimizes DOM manipulation, leading to improved performance.
Unidirectional Data Flow
Unidirectional Data Flow in React.js is a design pattern where data is managed in a single direction, typically from parent components to child components. This one-way flow ensures predictable data handling,and maintains application state by avoiding complex bidirectional data flows, resulting in more maintainable and predictable React applications.
The React.js ecosystem is a vast collection of libraries, tools, and resources that complement React. It includes state management solutions like Redux, UI component libraries such as Material-UI, build tools like Webpack, and various extensions for routing, testing, and more, fostering efficient and feature-rich development of React applications.
