Web development is the process of creating and maintaining websites and web applications. It encompasses a wide range of tasks, from front-end development, which involves designing the user interface and ensuring a seamless user experience, to back-end development, which focuses on server-side programming, databases, and application logic. Modern web development often employs a variety of technologies, such as HTML, CSS, JavaScript, and frameworks like React or Angular for the front end, and Node.js, Python, or Ruby on the back end. With the growing importance of responsive design and mobile optimization, web developers must also consider how their creations function across different devices and screen sizes. As the digital landscape evolves, staying updated with the latest trends and best practices in web development is essential for building effective and engaging online experiences.
