I actually didn’t know much about the front-end and back-end before, but after solving my doubts on the browser, I got a little understanding and compiled it into an article for your reference.
Front-end and back-end are two different fields in web development. What is the difference between these two fields? How to choose these two different fields rationally?
The programming world is equivalent to a fascinating stage, and front-end development and back-end development are equivalent to two different areas. One is equivalent to the stage, eye-catching, and the other is equivalent to behind the scenes, helping the front of the stage to perform better. !

I. Introduction
front end
The front-end refers to the interface visible to users . The front-end page of a website is the page development of a web page, which mainly involves websites and apps. Users can see things from the App screen or browser. For example, special effects, layout, pictures, videos, audio and other content on the web page. Simply put, everything you can see from the App screen and browser belongs to the front end.
rear end
The back-end refers to things that are invisible to users . It usually interacts with front-end engineers and saves and reads website data. Relatively speaking, the back-end involves much more logic code than the front-end. The back-end considers the bottom layer. Implementation of business logic, stability and performance of the platform, etc. Back-end development is "server-side" development, which mainly involves the "back-end" of the software system. For example, servers used to host website and app data, and middleware placed between back-end servers and browsers and apps, all belong to the back end. Simply put, the stuff you don’t see on the screen but that is used to power the front end is the backend.
personal opinion
According to everyone's interest in different things, you can choose based on your own interests. If you are more interested in graphics, interfaces, etc., you can choose the front end; however, if you are more interested in how to improve the efficiency of the website If so, you can choose the backend. Of course, this is not absolute. You still have to make a decision based on your actual situation (salary needs, etc.).
2. Comparative analysis of the two
Front-end and back-end have different professional skill requirements, and their developer responsibilities are also different.

2. Provide simple and easy-to-use design
3. Build a visually appealing website
4. Ensure that the look and feel of the website remains consistent across various browsers
rear end
Skill
Every company has different requirements for back-end development
But there are always a few requirements that are the same:
1. It is required to master a mainstream programming language: Golang/C/C++/Java/Python
2. Familiar with Linux, etc.

3. Build system and data analysis architecture
3. Front-end and back-end learning routes

4. Introduction to full-stack development
Working on both front-end and back-end development, they are called full-stack developers.
I think full stack development has both advantages and disadvantages. Although the number of developers can be reduced to half of the original number, their level has also been reduced accordingly. After all, developers who specialize in front-end or back-end development will always know more about a single field than developers who know both fields at the same time.
5. Personal suggestions
It doesn't matter what the development prospects of the front-end and back-end industries are, because as long as the IT industry continues to develop, these two positions will always be needed. So throw those thoughts aside and just think about which one is right for you rather than simply which one has better job prospects, front-end or back-end. After you have thought about it, you should calm down and work hard on the path you have chosen, so that you will not be treated badly in the future.
