Frontend and Backend Explained

When you use a website, two parts are working together: the frontend and the backend.

The frontend is everything you see and interact with buttons, forms, pages, and animations. The backend is everything happening behind the scenes. It processes data, applies logic, and decides what should happen.

They communicate constantly. When a user does something on the frontend, like clicking a button or submitting a form, the frontend sends a request to the backend. The backend processes that request, works with data if needed, and sends a response back. The frontend then updates what the user sees based on that response.

For example, during login, the frontend shows the form and collects user input, while the backend checks if the credentials are correct and returns a result. The frontend then shows either a success message or an error.
