How many knowledge points are there in the web front-end?
With the rapid development of the Internet, Web front-end technology has become a very important branch of the IT industry. Web front-end engineer is an emerging profession that requires a high technical level and innovative thinking. In order to achieve stable development in this industry, Web front-end developers must continue to learn and master various front-end knowledge points.
Web front-end knowledge points are very extensive, including Web development, web design, user experience design, front-end framework and other aspects. If you want to become a qualified Web front-end developer, you need to master the following knowledge points:
- HTML and CSS technology
HTML and CSS technology are the foundation of Web development , is the basis of web design. HTML is used to describe the structure of the page, and CSS is used to describe the style, layout, etc. of the page. Mastering these two technologies is a basic requirement for Web front-end engineers.
- JavaScript language
JavaScript is a powerful Web scripting language and one of the most important languages in Web front-end development. JavaScript can realize interactive effects, dynamic effects, etc. on web pages, and is widely used.
- Responsive web design
Responsive web design is a very important direction in modern web design. It allows web pages to adjust adaptively according to the size of different devices. You need to learn to use CSS technology and responsive web design framework for implementation.
- Ajax technology
Ajax technology is a technology used to realize asynchronous data transmission, which can quickly load network data and improve user experience. Requires an in-depth understanding of the principles and applications of Ajax technology.
- Application of jQuery library
jQuery is a lightweight JavaScript library that can be used to write JavaScript code. jQuery is very convenient and easy to use, and is one of the most widely used libraries in web front-end development.
- Front-end framework
Front-end framework can help quickly build high-quality, high-performance web applications. Commonly used front-end frameworks include Bootstrap, AngularJS, React, etc., which require users to have an in-depth understanding of their principles and usage.
- SEO
SEO refers to search engine optimization, which mainly optimizes the structure and content of web pages to make web pages rank higher in search engines. You need to master SEO techniques to improve the exposure of your website.
- Web Security
Web security mainly refers to protecting the security of web applications. You need to learn to use JavaScript to write secure code to prevent attacks such as XSS and CSRF.
In general, Web front-end technology is very extensive, and there are many knowledge points that need to be mastered. Web front-end developers need to have a solid technical foundation. At the same time, they must constantly update their knowledge reserves and understand the latest technological trends and cutting-edge technologies in order to remain invincible in the industry.

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 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

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.

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.

React is a JavaScript library for building user interfaces, with its core components and state management. 1) Simplify UI development through componentization and state management. 2) The working principle includes reconciliation and rendering, and optimization can be implemented through React.memo and useMemo. 3) The basic usage is to create and render components, and the advanced usage includes using Hooks and ContextAPI. 4) Common errors such as improper status update, you can use ReactDevTools to debug. 5) Performance optimization includes using React.memo, virtualization lists and CodeSplitting, and keeping code readable and maintainable is best practice.

The React ecosystem includes state management libraries (such as Redux), routing libraries (such as ReactRouter), UI component libraries (such as Material-UI), testing tools (such as Jest), and building tools (such as Webpack). These tools work together to help developers develop and maintain applications efficiently, improve code quality and development efficiency.

React is a front-end framework for building user interfaces; a back-end framework is used to build server-side applications. React provides componentized and efficient UI updates, and the backend framework provides a complete backend service solution. When choosing a technology stack, project requirements, team skills, and scalability should be considered.
