A design system is a collection of reusable components, guidelines, and principles that help ensure consistency and efficiency in design. It provides a framework for designing and building a product or service, and helps to maintain a cohesive and consistent user experience across different platforms and devices.
A design system typically includes a set of design principles, visual style guidelines, UI components, typography, color palettes, and other design elements. These components can be used and re-used across different projects, making it easier to maintain consistency in design and to move quickly from idea to implementation.
