As a person who wants to do IT, what are the advantages and disadvantages of going front-end and back-end?

The front end mainly shows the work of layers. More popularly speaking, it is what the user directly faces. So focus on visual effects and interactive effects. For the front-end circle, the "wheel" iteration is very fast, and a concept may flourish soon. For example, mvvm in recent years. Getting started at the front end is relatively simple. The front end mainly studies html, css, js, especially js, and now js's status is getting higher and higher. A front-end benchmark is js skills. The front end can get started quickly and fight.

The back end focuses on data processing, and technology stack's demand may be more complicated. In addition to understanding the back-end programming language, you need to master some middleware, such as web container, message middleware, cache middleware, load balancer and so on. Moreover, there are high requirements for the performance and even concurrency of the system. But the back-end technology is slow to land, and evolution takes time to pursue stability. The back end is the engine, which provides data and logic support for web, mobile and IoT. The technical level of the back end needs time and practice to accumulate slowly.

In fact, both directions have high requirements for your learning ability and logical ability. You can't sit back and relax when you enter the door If you don't study, you will be easily eliminated.
