1 Introduction
React is a JavaScript library for building user interfaces. It provides component-based programming, declarative programming, JSX syntax, etc. to facilitate developers to write reusable and combinable UI components, making the presentation of Web pages more flexible and dynamic. This article will lead readers from basic knowledge to practical projects to master the basic concepts, core mechanisms and usage skills of the React framework step by step, helping everyone to easily cope with increasingly complex front-end development scenarios. Reading this article can help you quickly master the application methods and characteristics of the React technology stack, and build high-performance web applications that are interactive, beautiful, and scalable.
What is React?
React is an open-source JavaScript library for building user interfaces. Its main functions include:
- JSX - JavaScript + XML (an XML-like markup language)
- Componentization - Split complex interfaces into multiple small modules for management
- One-way data flow - passing messages through props between parent and child components, making data flow between components easier
- Virtual DOM - DOM operations in the rendering process are performed through virtual DOM objects, which is more efficient
- Routing - Provides a Router module that supports different URLs and state switching
- Hooks - provides a series of hook functions, allowing developers to customize functions
- Server-side rendering - supports server-side rendering to improve the rendering speed of the first screen
To sum up, React is currently the most popular JavaScript framework and one of the hottest technologies in the field of web development. Learning React can help you implement complex interactive interfaces and high-performance web applications.
