What technologies does front end development learn to adapt to the demands of the job?

The prospect of the web front-end is very good, a major like the web front-end is still better in a first-tier city, the faculty can keep up, and the salary of employment is also considerable, and learning the web front-end can be <> in the order of the roadmap

The complexity of front-end logic mainly lies in the implementation of data + UI + interaction, such as a simple multi-tab function, which can be implemented with CSS and JS, JS can be hidden by switching Remove DOM or adding ClassName, although the effect can be achieved, Remove DOM cannot be in the state of the original structure, and it is difficult to initialize the state by adding ClassName CSS. In addition to this, it may be necessary to do compatibility processing + responsiveness to the browser. Then suddenly there is a business requirement that says to add an iframe to embed in other people's pages, or change the effect, if the previous development is not reasonable, basically have to be redone.

Compared with the backend, only the data model is output to the front-end, and if the business does not need any fields, or even the front-end does not need to read them, there is no need to change them. We have refactored several major business platforms, the front-end basically has to be redeveloped (the effect and interaction are completely different), and the back-end model and database can be reused, expanded, and upgraded progressively. This is also a problem that leads to the need for a heap of people to work the front end.

1. The three basic skills, JS, CSS, HTML, are front-end engineers.

The foundation of capabilities, any framework, tool, and library is based on these three. This is the hard power that determines the height that can be achieved throughout the front-end career, as well as the technology stack in the back.

The smoothness of the expansion and the results that can be achieved.

2. The front-end engineer is first of all an engineer, and doing the project is doing the project, so knowing how to run the front-end part of the project is another essential skill.

Grunt, Gulp, and Webpack are all well-known engineering tools, and as long as these tools can be used proficiently, they basically meet the requirements of engineering capabilities. But if you want to get an offer at the next level, it's essential to understand how it works. The fundamental role of these tools is to deal with resources, including compression and packaging, local server setup, etc.

3. Debugging ability is necessary, if you are still using alert and console to debug the program to locate the problem, then you do not meet the requirements.

Learn how to use chrome debugging tools, elements to view elements, network to view network requests, sources to view**, and set breakpoints.

Locate the problem and call stack to view the call stack. This ability is rarely mentioned, but mastering these skills will not only give you extra points in interviews, but more importantly, you will be able to play a role in real projects in the future.

4. Teamwork ability.

It refers to git, which is essential in project development, using git proficiently, mastering common commands, and learning to resolve conflicts.

5. The use of Vue, React is the two most popular frameworks at present, and being able to use it proficiently is the basic requirement, if you want to stand out from the crowd of job seekers, you also need to understand the principle, or that sentence, the gap between you and the offer is the gap between use and implementation. Try to understand the principles of virtual dom, the principle of reactivity, the comma physics of bidirectional data binding.

6. The project experience should be reliable, not "imitating a few pages", but the experience of the "project", which is the experience of the whole process of the project from 0 to 1, what pitfalls were encountered in the process, how to solve them, and how to think in the process of solving.

Thanks for the invite! I mainly write the back-end ** brother trace segment. I don't copy other people's application requirements from recruitment, but I will say a few points from the perspective of work.

1.Ability to write CSS.

2.Master JS and jQuery, and be able to manipulate pages flexibly.

3.Have your own ideas about the ease of use of the page.

4.The page interacts well.

5.The interface specifications of the back-end interaction are uniformly formulated to facilitate the front-end development.

6.You can write simple controls yourself, which is easy to use and easy for others to call.

7.**Specifications are easy to read.

The above envy is my own experience in the front-end requirements, from the perspective of actual development. Hope it helps!
