Frontend-backend separation refers to the architectural practice of separating the user interface from the server-side logic, allowing for independent development and deployment.

Frontend-backend separation is an architectural practice in web development that involves decoupling the user interface (frontend) from the server-side logic (backend). This separation allows for independent development, testing, and deployment of each part, enhancing flexibility and scalability. In a typical full stack application, the frontend is responsible for the user experience and interface, often built using HTML, CSS, and JavaScript frameworks like React or Vue.js. The backend, on the other hand, handles business logic, database interactions, and API management, typically built with server-side frameworks like Django or Flask. By separating these two layers, developers can work on the frontend and backend independently, enabling teams to specialize in their areas of expertise. This separation also facilitates the use of different technologies for each layer, allowing teams to choose the best tools for their needs. Moreover, it simplifies the process of scaling applications; if the backend needs to handle increased traffic, developers can optimize server performance without affecting the frontend. Overall, frontend-backend separation promotes a more organized and efficient development process, leading to more maintainable and scalable applications.
