User interface libraries

User interface libraries are collections of pre-made tools, components, and design elements that developers use to build the visual parts of software or websites. They streamline the process by providing ready-to-use buttons, menus, forms, and layouts, ensuring consistency and saving development time. These libraries help create interfaces that are both functional and visually appealing, adhering to good design principles. Examples include libraries like React, Bootstrap, and Material-UI, which facilitate the development of user-friendly and responsive digital experiences without needing to build components from scratch each time.
