Among computer programmers, front-end programmers and back-end programmers are two important technical positions. Front-end programmers are mainly responsible for the design, interaction and user experience of the website, while back-end programmers are mainly responsible for the data processing and security of the server. So what does the web front end do?
Web front-end: Overview
Web front-end technology refers to website front-end development technology, also called client technology, which mainly refers to the design and implementation of some interfaces of the website. Web front-end programmers need to master technologies such as HTML, CSS, and JavaScript, and use these technologies to create and implement the front-end of the website.
Web front-end development technologies usually include responsive web design, CSS3, HTML5, JavaScript, jQuery, AJAX, Angular, React and other technologies. Mastering these technologies is very important for front-end programmers.
Responsibilities of Web front-end programmers
Web front-end programmers need to be responsible for the front-end development tasks of the website, including:
1. Website design: Web front-end programmers must first do The most important thing is website design. Website design is the core of front-end development. Developers need to design the theme, layout, color and overall style of the website. To do this, you need to use CSS, HTML, and image design techniques.
2. Interface development: Website interface development is also one of the responsibilities of Web front-end programmers. Front-end programmers need to use technologies such as Css, HTML, JavaScript and other technologies to develop the user interface of the website.
3. Browser compatibility processing: Front-end programmers need to consider the compatibility of the website on different browsers. Today, there are thousands of web browsers on the World Wide Web, which means web front-end programmers need to ensure that websites run correctly on a variety of different browsers.
4. Collaborative development: Web front-end programmers and back-end developers need to work together, and joint development is required when realizing data interaction between the Internet.
5. Website optimization: Front-end developers also need to be responsible for optimizing the website, including optimizing website code, significantly improving page loading speed, page performance, etc.
Skillset: Skills required by Web front-end technicians
Web front-end technology is a complex area that requires technicians to have the following skills and technical skills:
- HTML and CSS: HTML and CSS are the cornerstones of web front-end development technology. HTML is responsible for the structure and content of website pages, and CSS is mainly responsible for the style and layout of website pages. As a demanding front-end developer, it is very important to master HTML and CSS.
- JavaScript and jQury: JavaScript and jQury are technologies that make the Web front-end dynamic, interactive, and more attractive. To become an experienced web front-end software engineer, mastering these two technologies is a must.
- AngularJS and ReactJS: AngularJS and ReactJS are one of the most popular JavaScript frameworks. They are widely used in process development. AngularJS is mainly responsible for handling the business logic of web applications, and ReactJS is mainly responsible for handling the view layer of web applications. (Note: React can also do back-end rendering, and can basically be separated and collaborated with the front-end view)
- Process and integration tools: In Web front-end technology, process and integration tools are already an indispensable part. Such as eslint, Webpack, etc. are very popular web front-end technology tools.
- Design skills: Good design skills can provide rich materials for front-end development. By conceiving and improving prototypes, using some popular design software such as Photoshop, Sketch, Invision, etc., you can improve the efficiency of front-end development and become a Efficient web front-end developer.
The development prospects of Web front-end technology
With the popularization of Internet technology, the development of Web front-end technology has been developing rapidly. Many companies now need to understand Web front-end technology, and these companies are building various software based on Web front-end technology. Innovation and progress in front-end technology and the deepening of Internet penetration provide good prospects and more opportunities for front-end technicians.
Conclusion
Web front-end technology is an important technology. With the continuous development of Internet technology, Web front-end technology will continue to develop. Learning Web front-end technology requires mastering technologies such as HTML, CSS, JavaScript, jQury, AngularJS and ReactJS, processes and integration tools. At the same time, the continuous development of Web front-end technology provides programmers with broad development prospects and opportunities.

HTML and React can be seamlessly integrated through JSX to build an efficient user interface. 1) Embed HTML elements using JSX, 2) Optimize rendering performance using virtual DOM, 3) Manage and render HTML structures through componentization. This integration method is not only intuitive, but also improves application performance.

React efficiently renders data through state and props, and handles user events through the synthesis event system. 1) Use useState to manage state, such as the counter example. 2) Event processing is implemented by adding functions in JSX, such as button clicks. 3) The key attribute is required to render the list, such as the TodoList component. 4) For form processing, useState and e.preventDefault(), such as Form components.

React interacts with the server through HTTP requests to obtain, send, update and delete data. 1) User operation triggers events, 2) Initiate HTTP requests, 3) Process server responses, 4) Update component status and re-render.

React is a JavaScript library for building user interfaces that improves efficiency through component development and virtual DOM. 1. Components and JSX: Use JSX syntax to define components to enhance code intuitiveness and quality. 2. Virtual DOM and Rendering: Optimize rendering performance through virtual DOM and diff algorithms. 3. State management and Hooks: Hooks such as useState and useEffect simplify state management and side effects handling. 4. Example of usage: From basic forms to advanced global state management, use the ContextAPI. 5. Common errors and debugging: Avoid improper state management and component update problems, and use ReactDevTools to debug. 6. Performance optimization and optimality

React can be embedded in HTML to enhance or completely rewrite traditional HTML pages. 1) The basic steps to using React include adding a root div in HTML and rendering the React component via ReactDOM.render(). 2) More advanced applications include using useState to manage state and implement complex UI interactions such as counters and to-do lists. 3) Optimization and best practices include code segmentation, lazy loading and using React.memo and useMemo to improve performance. Through these methods, developers can leverage the power of React to build dynamic and responsive user interfaces.

React is a JavaScript library for building modern front-end applications. 1. It uses componentized and virtual DOM to optimize performance. 2. Components use JSX to define, state and attributes to manage data. 3. Hooks simplify life cycle management. 4. Use ContextAPI to manage global status. 5. Common errors require debugging status updates and life cycles. 6. Optimization techniques include Memoization, code splitting and virtual scrolling.

React's future will focus on the ultimate in component development, performance optimization and deep integration with other technology stacks. 1) React will further simplify the creation and management of components and promote the ultimate in component development. 2) Performance optimization will become the focus, especially in large applications. 3) React will be deeply integrated with technologies such as GraphQL and TypeScript to improve the development experience.
