In addition to mastering the learning route, front-end learning must pay attention to the key points of knowledge!

For front-end learners, mastering the necessary knowledge and skills is a necessary process, so for the front-end, what are the necessary skills to master?

Summarized the following six:

1, html

This is the simplest and most fundamental. To master the div, formtable, ulli, p, span, and font tags in html, these are the most commonly used, especially div and table. div is used for construction, and table can also be used for construction, but it is not flexible. The basic table is used to deal with data.

Two, css

The css mentioned here does not include css3. As we usually see the requirements of web front-end development engineers, one of them will use css+html or css+div to stop the interface construction, so css is used to assist html to construct and display. We call it "css style", why do we say css+div? Since I said above that div is the primary tool for html construction, so div is the tool for focus control! Then css must be used with div. CSS must be proficient in grasping float, position, width, height, as well as the maximum and minimum to deal with, will use 100%, overflow, margin, padding, etc., these are styles related to the structure, we must grasp it.

Three, js

Maybe the first two people feel that they can still feel it after learning. It hurts when you see js. Actually, the introduction of js is very simple. There are no need to use many tools. You only need to pick it according to a certain id or name. Go to the page dom or style, or value, and then assign a value to the element tag of a certain id or name, or append data, and chase html. This is the control related to the data, and then the data logic determines that the situation is nothing more than Jumping, popping, hiding, etc., connecting all of these to the others is practical. The code is not difficult at all. After knowing these basic js, the others will be directly Baidu. Then, if you watch too much and use too much, nothing will be a problem.

Four, jquery

Jquery is a js plug-in that encapsulates a set of js. The purpose is to control it more conveniently, write less code, and get started with jquery is very simple. Those are the same as js, but replaced with jq. Code. Baidu is enough.

Five, vue and react

At present, these two frameworks are necessary for many companies to master, and for those who want to enter the industry, they are indeed essential.

Six, front-end interview

Technical passion. When I interview people, I rarely use "question-style interviews". I don’t deliberately ask a technical question for you to solve and make the other party nervous. I mainly rely on guidance, and I will lead to some technical topics, such as some popular topics. Topics, some technical hotspots and difficulties, some new tools.

Attitude. I talked about this topic when I was out for dinner with my friends at noon today. Start-up companies are really a pit sometimes, and they need to face many unsatisfactory issues, such as salary, benefits or business processes. What is your attitude toward these issues? Why leave the last company?

The above are some of the precautions for front-end learning for everyone. The most important thing is front-end learning. Front-end learning suggests that you still choose training, because the front-end technology is developing fast. If you study by yourself, you may learn some old versions of knowledge. Can't keep up with technical demands at work. Training institutions are often based on the development of front-end technology to update front-end courses so that students can learn the latest front-end knowledge. Like Aichuang Classroom, it is a training institution specializing in front-end education. The former Baidu front-end architect, Zhang Rongming personally led the lectures to teach the whole process; the teaching is mainly based on practical courses. Teacher Zhang has excellent front-end technology. Every year, many students come to learn and teach countless senior front-end engineers. Have employment. Recently, the Ai Chuang class is fully taught by teacher Zhang Rongming himself. The small class is a small class with limited places. If you want to register, contact me! Nowadays, many people are at a loss when choosing a school. In fact, they can experience it in the field. After all, the most important thing is to suit them.

The front-end industry is developing rapidly. Many companies are online and inseparable from the Internet, and front-end talents are the most important part of them. Mastering these knowledge points, I believe it will be helpful on the road to learning the front-end.
