React

The library for web and native user interfaces

React 介绍

React is a free, open-source JavaScript library for building dynamic and interactive user interfaces on web and native platforms. By using reusable components, it streamlines the development of complex applications, making state management and performance optimization easier. Its declarative nature allows developers to describe the UI state, resulting in more predictable and maintainable code. The virtual DOM enhances app responsiveness by minimizing direct DOM manipulations. Backed by a vibrant community and extensive resources at react.dev, React empowers developers of all levels to create efficient and scalable applications.

常见问题

What is React used for?

React is used for building dynamic and interactive user interfaces for web and native applications, such as single-page apps, dashboards, and mobile apps.

How does the virtual DOM improve performance?

The virtual DOM creates a lightweight copy of the actual DOM and only updates the real DOM when changes are detected, minimizing direct manipulations and boosting app speed.

Is React free to use?

Yes, React is completely free and open-source, with no licensing fees, making it accessible for all developers.

What are reusable components in React?

Reusable components are modular pieces of UI that can be used multiple times in an application, promoting code reusability, maintainability, and scalability.

Can React be used for mobile development?

Yes, React can be extended with React Native to build native mobile applications for iOS and Android, using the same core principles.
