Key features and characteristics of React.js
Component-Based Architecture: React.js encourages the creation of reusable UI components that encapsulate their own logic and state. Components can be composed together to build complex UIs, making the codebase more modular and maintainable.
Virtual DOM: React.js uses a virtual representation of the actual DOM (Document Object Model), known as the Virtual DOM. When the state of a component changes, React efficiently updates only the necessary parts of the actual DOM, resulting in improved performance and faster rendering.
Declarative Syntax: React uses a declarative approach, where developers describe what the UI should look like based on the current state of the application. This makes it easier to reason about the UI and its behaviour.
Unidirectional Data Flow: React follows a unidirectional data flow, meaning that data changes flow in a single direction, from parent components to child components. This helps in maintaining the predictability of the application's state.
React Native: React.js has a sibling framework called React Native, which allows developers to build mobile applications for iOS and Android platforms using the same component-based approach and React concepts.
Community and Ecosystem: React.js has a vibrant community and an extensive ecosystem with numerous third-party libraries and tools. This ecosystem enables developers to leverage additional functionalities and streamline their development process.
Performance Optimization: With its Virtual DOM and efficient rendering strategies, React minimizes the number of actual DOM manipulations, leading to better overall performance and a smoother user experience.
