Component-Based Architecture
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.
Virtual DOM:
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.
JSX (JavaScript XML):
JSX (JavaScript XML) is a syntax extension in React.js that blends JavaScript and HTML-like code. It simplifies UI development by allowing developers to define the structure of components in a more intuitive way. JSX is transpiled into JavaScript, enabling React to efficiently render dynamic content while maintaining a component-based approach.
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.
React Router
React Router is a JavaScript library for handling client-side routing in React.js applications. It allows developers to create multiple views or pages in single-page applications, managing route-based navigation. It enables route definition, parameter passing, and dynamic content rendering, enhancing the user experience and creating a more structured application flow.
Ecosystem
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.
