What do front-end and back-end mean?

Difference: The front-end is responsible for user interface design and interaction, including web pages, images and other content that users see in the browser. The backend is responsible for processing data and performing logical operations, including server-side scripts, databases, and APIs.

Front-end and back-end are two major aspects in web development that play different roles in building a complete web application.

The front end, as the name suggests, refers to the part that users can directly see, that is, the presentation interface of the website. This includes web pages, images, audio, video, and everything a user sees in the browser. The main job of a front-end developer is to design and develop user interfaces using technologies such as HTML, CSS, and JavaScript to ensure that users can interact with web applications easily and intuitively. The front-end work also includes converting the artistic design renderings into web pages that can be run by the browser, and cooperating with the back-end to realize the display and interaction of web page data.

The backend is the part that users cannot see and is mainly responsible for processing data and logical operations. Back-end developers need to write code that manages the Web server to implement data processing, logic control, and interaction with the front-end. Back-end content includes server-side scripts, databases, APIs, etc., which provide users with data service interfaces and process related business logic.

In general, the front-end focuses on the design and interaction of the user interface, while the back-end focuses on data processing and logic control. The two are interdependent in web application development. Only when the front-end and back-end work together can a complete and fully functional web application be realized.
