O desenvolvimento front-end centra-se na parte visual das aplicações Web, utilizando HTML, CSS e JavaScript para criar interfaces de utilizador. O desenvolvimento back-end centra-se nas tecnologias do lado do servidor e nas bases de dados, trabalhando nos bastidores para fornecer funcionalidades e armazenar dados a que o código front-end pode aceder e apresentar. Embora os programadores front-end e back-end tenham especialidades diferentes, trabalham em estreita colaboração para criar aplicações Web completas com interfaces apelativas e reactivas alimentadas por back-ends robustos.
Front-end development refers to the client-side of web development, focusing on everything the user visually interacts with and sees in their browser when they visit a website. Front-end developers are responsible for crafting the look, feel, and interactivity of a site using HTML, CSS, and JavaScript to build the front-end architecture. Their work includes coding and programming the visible components like page layouts, buttons, menus, forms, and images that users engage with. The front-end code executes in the user's web browser, determining what is displayed and how elements interact with the user.
Back-end development encompasses the behind-the-scenes server-side technology powering websites and web applications. While front-end development handles the interface and presentation, back-end developers build and maintain the background infrastructure and databases that enable web and mobile applications to actually function. Using server-side languages like PHP, Ruby, Python, and .NET, back-end programmers write code to perform server processing, connect to databases, handle user authentication and authorization, execute business logic, manage APIs, and deliver dynamic content to the client-side. The back-end handles complex functionality like data processing, application logic, security, integration, and connecting with other systems while safely retrieving and storing data in databases.
