The difference between the front-end and the back-end
1. Different languages: the front-end code is mainly run on the client side; the back-end code is mainly run on the server side.
2. The direction of thinking is different from user interaction: the front section mainly considers how to make users feel more comfortable to use, considers interface layout, interaction effects, page loading speed, etc., and mainly focuses on the part that users can see: the back end More consideration is given to business logic, database table structure design, server configuration, load balancing, data storage, cross-platform API design, medical record pictures, etc., and more is to consider the parts that users cannot see to ensure that business logic processes data Rigorous to ensure the performance of data throughput
3. Different stability: the front-end is mainly afraid of frequent changes in design drafts, layout styles, and interactive effects; the back-end is mainly afraid of business logic changes, or the stability of the front-end when the scale of use
increases What is development?
The front-end is the front-end part of the website, running on the PC, mobile and other browsers to display the webpages for users to browse. With the development of Internet technology, the application of HTML5, CSS3, and front-end frameworks, the cross-platform responsive web design can adapt to various screen resolutions, and the perfect dynamic design brings users a very high user experience.

The back-end refers to the content that runs in the background and controls the front-end. It is mainly responsible for program design architecture ideas, database management, etc. The backend is more applied to the database and interacts to process the corresponding business logic. What it needs to consider is how to implement functions, data access, platform stability and performance, etc. It involves dynamic languages such as PHP, ASP, JSP and so on.
