What do you need to learn to be a web front-end engineer?
First of all, we should master the basic Web front-end development technologies, including CSS, HTML, SEO, DOM, BOM, Ajax, JavaScript and so on. While mastering these technologies, we should also clearly understand their compatibility in different browsers, rendering principles and existing bugs. Secondly, 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, we should learn to use various tools for auxiliary development. Fourthly, in addition to technical knowledge, we should master theoretical knowledge, including code maintainability, component availability, hierarchical semantic template and browser hierarchical support, etc. It can be seen that it is really not easy to make a seemingly simple web page better and more professional. This is the characteristic of front-end development, and it is also the reason that puzzles many people. Such a complex knowledge system is difficult for beginners to learn, and for veterans, they often don't know what to learn next. Code quality is one of the key issues in front-end development. For example, there may be countless schemes to realize a website interface, but some schemes will have higher maintenance costs, some schemes will have performance problems, and some schemes will be easier to maintain and have better performance. The key factor here is code quality. CSS, HTML and JavaScript have different characteristics and different requirements for code quality, but they are inextricably linked.
Web front-end engineers need to study and practice before, master the production of static web pages, and be able to flexibly use html+css language and Div+css layout to make excellent static pages.
Can use JavaScript language to make excellent dynamic effect and user experience, and can simply make and use JavaScript function framework.
Be able to use Html5 to create beautiful web effects, as well as the development and production of mobile applications and mixed applications.
How to be an excellent web front-end engineer?
A good Web front-end development engineer should have both breadth and depth in knowledge system, so it is difficult for many large companies to recruit ideal front-end development engineers even if they pay high salaries. The focus now is not on explaining technology, but on explaining skills. There is no black and white technology, only right and wrong, and skills are different. I used to know that Photoshop and Dreamweaver could make web pages, but now it is not enough to master these. No matter the development difficulty or the development method, the current Web page production is closer to the traditional website background development, so it is no longer called web page production, but called web front-end development. Web front-end development has become more and more important in product development, which needs professional front-end engineers to do well. Professionals in this field have been favored in recent two years. Web front-end development is a very special work, involving a wide range of knowledge, both specific technologies and abstract ideas. Simply put, its main function is to better present the interface of the website to users. Therefore, an excellent front-end development engineer not only needs to master various technologies necessary for the front-end, but also needs to master other technologies, a little background knowledge, a certain understanding of website architecture, and a certain SEO website optimization technology in order to be called an "excellent web front-end development engineer". In addition to technology, it takes some time to precipitate yourself. A senior and excellent web front-end development engineer is the talent that every large enterprise yearns for. According to industry insiders, it is better to recruit people with high salaries than to train relevant technical talents by insurance companies themselves.
