Web development is the process of creating and maintaining websites and web applications.
In the front-end development, web developers focus on designing and implementing the user interface (UI) and user experience (UX) of a website.
On the other hand, back-end development involves working with databases, servers, and server-side programming languages to handle data storage, retrieval, and processing.
In summary, web development is a multidisciplinary field that combines programming, design, and problem-solving skills to create and maintain websites and web applications.
