What is the main focus of front-end development in web applications?

The primary focus of front-end development in web applications is centered around the user interface (UI) and user experience (UX). This area of development is dedicated to creating everything that users interact with directly on a website or web application. This includes the layout, design, and interactivity of the application's interface, making it visually appealing, functional, and user-friendly.

Front-end developers typically use technologies like HTML, CSS, and JavaScript to build responsive and accessible interfaces that cater to user needs and preferences. Their work ensures that users can navigate the application easily, interact with its elements, and have an overall positive experience.

Other aspects of web development, such as database management, server-side scripting, and network security measures, fall under back-end development and other specialized disciplines. These areas are crucial to the overall functionality and security of web applications but do not directly pertain to what users experience while interacting with the application. This clarity highlights why the focus of front-end development is distinctly on user interface and user experience.
