Understanding Web front-end technology: What does the Web front-end do?

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:

1. 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.
2. 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.
3. 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)
4. 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.
5. 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.
