React combines JSX and HTML to improve user experience. 1) JSX embeds HTML to make development more intuitive. 2) The virtual DOM mechanism optimizes performance and reduces DOM operations. 3) Component-based management UI to improve maintainability. 4) State management and event processing enhance interactivity.

React components can be defined by functions or classes, encapsulating UI logic and accepting input data through props. 1) Define components: Use functions or classes to return React elements. 2) Rendering component: React calls render method or executes function component. 3) Multiplexing components: pass data through props to build a complex UI. The lifecycle approach of components allows logic to be executed at different stages, improving development efficiency and code maintainability.

Vue 2's reactivity system struggles with direct array index setting, length modification, and object property addition/deletion. Developers can use Vue's mutation methods and Vue.set() to ensure reactivity.

React is the preferred tool for building interactive front-end experiences. 1) React simplifies UI development through componentization and virtual DOM. 2) Components are divided into function components and class components. Function components are simpler and class components provide more life cycle methods. 3) The working principle of React relies on virtual DOM and reconciliation algorithm to improve performance. 4) State management uses useState or this.state, and life cycle methods such as componentDidMount are used for specific logic. 5) Basic usage includes creating components and managing state, and advanced usage involves custom hooks and performance optimization. 6) Common errors include improper status updates and performance issues, debugging skills include using ReactDevTools and Excellent

TypeScript enhances React development by providing type safety, improving code quality, and offering better IDE support, thus reducing errors and improving maintainability.

The article explains using useReducer for complex state management in React, detailing its benefits over useState and how to integrate it with useEffect for side effects.

Functional components in Vue.js are stateless, lightweight, and lack lifecycle hooks, ideal for rendering pure data and optimizing performance. They differ from stateful components by not having state or reactivity, using render functions directly, a

The article discusses strategies and tools for ensuring React components are accessible, focusing on semantic HTML, ARIA attributes, keyboard navigation, and color contrast. It recommends using tools like eslint-plugin-jsx-a11y and axe-core for testi
