What is the difference between frontend and backend
The difference between the front-end and the back-end is that the front-end is the part that we can directly view, mainly written in HTML, CSS and other languages; the back-end is the side that users cannot see and runs in the server, mainly through java , written in Python and other languages. (Recommended: php Chinese online live class (front-end and back-end applet))
In the process of web development, the front-end and the back-end are two The most commonly used terms, they play an important role in web development. The front end is what we see of the user interface and the back end is the part that we cannot see and interact with. Next, in the article, we will introduce the difference between the two in detail
What is the front-end?
The front end is the part that we can directly view, it involves everything that users can see, touch and experience. For example, the various graphics, buttons, pictures, navigation menus, etc. you see on the website. The front end is also called the "client side" because the action takes place on the client side which in this case is the user's side. Usually the client refers to a computer application, such as the web browser that is viewing it. Front-end development mainly involves designing websites. Use a combination of tools (including HTML, CSS and JavaScript) to create a visually appealing and user-friendly design interface[Recommended tutorial: Quick Start to Front-End Development】
What is the backend?
The backend is called the "server side" and is the part we cannot see. It is more like an indirect service provider for front-end development. It is the part of the system that does not have direct contact with the user. Unlike the frontend, it runs on the server side but communicates with the frontend to make sure everything is working properly. In every application, there's also a large portion of non-UI code that handles all the complex systems going on in the background. The people who handle the backend are usually programmers and developers.
Backend developers handle everything that doesn't involve generating a user interface, such as writing APIs, creating libraries, or adding utilities to everything created by web designers. They facilitate communication between the presentation layer and the business layer. They play a vital role in web development and their role is highly collaborative compared to front-end web designers. In short, backend web development is the combination of development and maintenance of the core functional logic of a software application. Simply put, back-end developers write code to make sure everything works properly on the front-end. Compared to web designers, they tend to spend more time figuring out logic and implementing algorithms to ensure the website functions properly. This is the brain of a website.

Difference between front-end and back-end
Meaning:
The front-end is the part of the website that is visible to the user, e.g. Graphical user interface (GUI) and command line, including design, navigation menus, text, images, videos, etc. In contrast, the backend is the part of the website that users cannot see and interact with. It's all about how everything works.
Function:
Both play a vital role in web development, and although they have considerable differences, they are like the same Two sides of the same coin. The front end is about the visual aspects of the website that users can see and experience. Instead, everything that happens in the background can be attributed to backend web development. It's more of an enabler of the front-end web experience.
Coding language:
The front end is also called the "client" instead of the backend, which is basically the "server side" of the application. Code languages for back-end web development include java, Ruby, Python, PHP, .Net and other languages. The most common front-end languages are HTML, CSS and JavaScript
