Front-end-utveckling fokuserar på den visuella sidan av webbapplikationer med hjälp av HTML, CSS och JavaScript för att skapa användargränssnitt. Backend-utveckling fokuserar på teknik och databaser på serversidan och arbetar bakom kulisserna för att tillhandahålla funktioner och lagra data som frontend-koden kan komma åt och visa. Även om frontend- och backend-utvecklare har olika specialområden arbetar de nära varandra för att bygga kompletta webbappar med tilltalande och responsiva gränssnitt som drivs av robusta backends.
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.
