What Are the Different Web Developer Jobs?

Web front-end development engineers are engineers who are engaged in web front-end development. The main work is to develop, optimize and improve the website. Web page production is a product of the Web 1.0 era. At that time, the main content of the website was static, and the behavior of users using the website was mainly browsing.

After 2005, the Internet has entered the Web 2.0 era, and a large number of desktop-like Web applications have emerged. As a result, the front end of the website has changed dramatically. Web pages no longer only carry a single text and picture. Various rich media make the content of the web pages more vivid. Software-based interactive forms on the web pages provide users with a better experience. These are based on front-end technology.

Web front-end development technology includes three elements:

There are two reasons for refactoring your own website:

First, according to

A good web front-end development engineer must have both breadth and depth in the knowledge system, so many large companies can hardly recruit ideal front-end development engineers even with high salaries. Now the focus is not on explaining the technology, but on the skills. Technology is either black or white, only right and wrong, and skill is different. In the past, Photoshop and Dreamweaver could be used to make web pages. Now it is not enough to master these. Regardless of the development difficulty or the development method, the current webpage production is closer to the traditional website background development, so it is no longer called webpage production, but Web front-end development. The role of web front-end development in product development has become more and more important, and professional front-end engineers are required to do well. Professionals in this area are highly favored. Web front-end development is a very special task, covering a wide range of knowledge, both specific technologies and abstract ideas. Simply put, its main function is to better present the user interface of the website.

Therefore, an excellent front-end development engineer not only needs to master the various technologies necessary for the front-end, but also masters other technologies, as well as a little background knowledge. At the same time, he must have a certain understanding of the website structure, and at the same time must master some SEO website optimization technology so that it can be called an "excellent web front-end development engineer". In addition to technology, it takes time to settle yourself. A senior excellent web front-end development engineer is a talent that every large enterprise desires. Industry insiders said that rather than recruiting people with high salaries, insurance companies would not be willing to train related technical talents themselves. ^[1]

How can we do better?

First, you must master basic web front-end development technologies, including: HTML5, CSS3, JavaScript, DOM, BOM, Ajax, SEO, etc. While mastering these technologies, you must also clearly understand their compatibility on different browsers Situation, rendering principles, and existing bugs.

Second, in the knowledge structure of a qualified front-end engineer, the basic knowledge of website performance optimization, SEO, and server-side must also be mastered.

Third, you must learn to use various tools to assist development.

Fourth, in addition to the technical level of knowledge, you must also master the theoretical level of knowledge, including the maintainability of code, the ease of use of components, hierarchical semantic templates and browser hierarchical support, and so on.

It can be seen that if it seems that simple web page production is better and more professional, it is really not easy. This is the characteristic of front-end development and why it confuses many people. Such a complicated knowledge system makes it difficult for novices to learn. For veterans, they often do not know what to learn next.

Code quality is one of the issues that should be considered in front-end development. For example, there may be countless schemes to implement a website interface, but some schemes have higher maintenance costs, some schemes have performance problems, and some schemes are easier to maintain and have better performance. The key influencing factor here is code quality. The characteristics of the three front-end development languages of CSS, HTML, and JavaScript are different, and the requirements for code quality are different, but they are inextricably linked.
