Web Development is the process of building and maintaining websites and web applications. It involves front-end development (client-side), which focuses on the visual aspects and user experience, and back-end development (server-side), which handles data processing and server logic. Web developers use programming languages, frameworks, and tools to create functional, responsive, and user-friendly websites that meet the needs of users and businesses. AI tools are transforming web development by automating coding tasks, enhancing user experience design, and streamlining development processes, allowing developers to build innovative web solutions more efficiently.
