Frontend development creates graphical user interfaces that turn raw data into a format humans can read. Users directly interact with everything on the frontend—navigation menus, design elements, buttons, images, and graphs. Frontend developers make sure content displays properly on devices of all sizes through frameworks and libraries.
Backend development handles server-side operations where data lives and processing happens. The backend can process thousands of different requests at once by combining techniques like request distribution across servers, caching, and data duplication. The backends’ strong infrastructure includes servers, databases, and server-side applications that power the frontend.
