Frontend, also known as client-side, refers to the part of an app or website that the user interacts with directly. It encompasses the user interface and all its elements including buttons, menus and forms. Frontend development involves the use of programming languages such as HTML, CSS and JavaScript to create and manage the user interface. The main goal of frontend development is to create a visually appealing, responsive and user-friendly interface. Frontend development is typically distinct from backend development, which involves the server-side logic and data management that supports the frontend. The separation of frontend and backend allows for more efficient development and maintenance and enables developers with different skill sets to specialise in each area.
