Language and technology:
- Front-end: Mainly using technologies such as HTML, CSS and JavaScript, as well as front-end frameworks and libraries such as React, Angular, Vue et al.
- Backend: Various programming languages and frameworks can be used, such as Java (Spring Boot), Python (Django/Flask), JavaScript (Node.js), etc.

- Backend: Responsible for storing, reading and processing data, interacting with the database, and returning processing results to the frontend.

Security:
- Front-end: Mainly focus on user-side security, such as preventing XSS (cross-site scripting attacks), CSRF (cross-site request forgery), etc.
- Backend: Responsible for handling application security, including data verification, user rights management, etc.

Running environment:
- Front-end: The code is executed in the user's browser, mainly running on the client.
- Backend: The code is executed on the server side, usually deployed and run on the server.
