What are the requirements of a good front-end development engineer?

The requirements for web front-end engineers are: they must master basic web front-end development technology, understand website performance optimization, server-side knowledge, be able to use various front-end tools for auxiliary development, and master theoretical knowledge.

Web development

A good Web front-end development engineer must have both breadth and breadth of knowledge system. It requires depth, so even if many large companies offer high salaries, it is difficult to recruit ideal front-end development engineers. The focus now is not on explaining technology, but more on explaining skills. Technology is not black and white, there are only right and wrong, and skills are a matter of opinion. In the past, you could create web pages just by knowing Photoshop and Dreamweaver, but now it is no longer enough to just master these. Whether in terms of development difficulty or development methods, current web page production is closer to traditional website back-end development, so it is no longer called web page production, but Web front-end development. Web front-end development plays an increasingly important role in product development, and professional front-end engineers are required to do it well. Professionals in this area have been highly favored in the past two years. Web front-end development is a very special job, covering a wide range of knowledge, including both specific technologies and abstract concepts. Simply put, its main function is to better present the website interface to users.

How can we do better?

First, you must master basic Web front-end development technologies, including: CSS, HTML, DOM, BOM, Ajax, JavaScript, etc. While mastering these technologies, you must also clearly understand them Compatibility, rendering principles and existing bugs on different browsers.

Second, in the knowledge structure of a qualified front-end engineer, 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 mastering technical knowledge, you must also master theoretical knowledge, including code maintainability, ease of use of components, hierarchical semantic templates and browser hierarchical support, etc. .

Summary:

Seemingly simple web page production, if you want to make it better and more professional, it really is not Simple. This is the characteristic of front-end development, and it is also the reason why many people are confused. Such a complicated knowledge system makes it difficult for novices to start learning, and for veterans, they often don’t know what to learn next.

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