So, how can you become a qualified web front-end engineer? Next, Qianfeng Chongqing web front-end will share with you what skills a qualified web front-end engineer has.
1. The basic structure of the web page (HTML, CSS)
HTML is a markup language, not a programming language. Tags and CSS are used to define how to display HTML elements. Therefore, beginners must have an in-depth understanding of the basic structure of web pages.
2. How does the browser display web pages
Browsers with different cores render web pages differently. At present, browsers have client-side debugging tools. When we optimize web performance, we need to know more about browser rendering and details. Let me talk about a more useful knowledge point: the current upper limit of parallel loading of browsers is 6, and older browsers will be different.
3. What cycle of web pages
Under different web frameworks, the life cycle of a page will be different, but it is generally the same: the client sends a GET request, the server returns the corresponding page, the client completes the operation and data, and then POSTs to the server. Be sure to understand the details of the data transfer (between the foreground and the background, between the pages).
四、DHTML DOM BOM JavaScript AJAX
This is the focus of web front-end development. We are dealing with them most of the time, so we must be proficient in these.
5. Server-side language development experience, PS image cutting technology
Web front-end development is somewhere between design and development, so you have to understand things at both ends. The editing language is interlinked. The server language has been written before, which is very useful for learning Javascript. The PS image cutting technology is indispensable for converting pictures into static HTML pages.
Six, browser compatibility
Due to historical reasons, browser compatibility has always been a place to torture web front-end engineers. Although there is a W3 organization, and some specifications have been formulated, although browser manufacturers are working hard to improve and approach their specifications, there are various types in the real network environment. The kernel and browsers of various versions have their place.
7. Quick learning ability and willingness to learn actively
The development of the web front-end is very fast. To engage in this industry, you must have the ability to learn quickly and the willingness to learn actively, so as to meet the requirements of web products. There is no absolute right and wrong in the Web front-end field. There are many ways to solve a problem, but we have to find a more suitable method. Finding a more suitable method requires experience to accumulate. In short, it is easy to get started with the Web front-end, but it is difficult to master it. , Need more willingness to learn actively.
8. Good communication skills
Excellent front-end engineers need to have good communication skills, because your work is closely related to the work of many people, such as project managers, designers, end users, and development engineers. Front-end engineers are located at the intersection of these types of people. You are required to take care of everything, balance the needs of these four types of people, and come up with a more appropriate plan. This shows that communication skills are more demanding for front-end engineers.
