Why do so many feel that the front end very simple technology?

The front is not simple, but the front end of the learning feedback is very direct, so to learn or understand a little front end of so many people, because change fonts, change pictures seems very simple, very simple front-end technology to produce judgments, pulled down the overall evaluation of.

In fact, misunderstandings have been in, for example: the front is the UI, very simple. The back-end is CRUD, very simple. Artificial intelligence is the controlled variable, very simple.

No front-end college courses, and front-end update too fast, leading to some teachers, or others FIELD understand the current front-end technology is still stuck doing a html page level. But relatively speaking, learning and employment threshold threshold contrast to the front of big data, machine learning, artificial intelligence is lower. But not to the point where very simple, if you really think it is very simple, in most cases is ignorant.

Front-end is very friendly, if not involve some complicated framework, without having to learn any programming language, html + css only need to be able to write a page, and bring the front end of the learning feedback is very obvious, ui will write html + css, a few lines of html and css page will be able to write a good look, thus leading to a lot of people think that the front end of technology is very simple.
 
 Getting Started Front is indeed very simple, but the difficulty lies in the front-depth study and knowledge of complex front-end, and if no one over to help, you will feel no clear line to be found, what often are used in what school, or according to their business needs to supplement knowledge, knowledge is very scattered, resulting in front of school behind forget. For the preceding engineer, the most important thing is to have a suitable learning path, from shallow to deep.

In recent years, the field of the development of front-end, front-end program now apes may not need a separate back-end complete a full application, that had not only cut plan to write the front page of the Times. In addition, the technology refresh cycle iteration front end is very short, almost every new frame out each year. So we have to keep learning.
Now front and past a big difference, from the development, compilation, build, unit testing, deployment, on-line publishing, more and more front-end engineering of the project, the endless stream of js framework of their respective ecosystem and updated version of the iteration, node of popular, popular ts of, webpack various building tools, code specifications, git version management, mobile terminal h5, mixed APP, native APP, applets, continuous integration, continuous deployment, sustained release, too many things need to be used, you say where simple?
 

In addition, the complexity of the front itself, should be fast, efficient and stable realization of business functions, and cross-platform compatibility and interfacial interaction is more important, especially in animation, 3D, VR them. Into the mobile Internet era, meaning a large extent is reflected in the front of the traffic. Based on the user experience and flexibility to promote low-cost carriers can get a large number of users

H5 + + APP is a small program for any one user's indispensable commercial companies, in the face of millions, one hundred million level user system, there is no front-end, web still in the web1.0 era, the page can only be used to navigate through the text a 5M the flow is enough to use a month. 10 years ago, this post is not the front, the front end is selected to promote the development of technology users, user demand after another, so front-end technology updates quickly iterative, meaning this is the tip of the existence and should be accepted, the development of the browser as well.

It's hard to imagine there is no front-end, Alipay, micro-channel, drops a taxi, take-away ... and so the US group, how to achieve and to a large user quality of service and experience.

The front is not without value proposition, is not reflected in the value of the non-user-oriented services and companies.
