The entire process of creating and managing browser-based websites or web apps is known as web development. It can be broadly classified into two categories: back-end development, which deals with the server, database, and logic (the "server-side"), and front-end development, which concentrates on the visual interface and user experience (the "client-side"). Full-stack developers are those that are proficient in both fields. By 2026, the field has progressed from basic page-building to "system thinking," in which websites are viewed as adaptive products that are intricately linked with AI and business automation tools.
