What are the design systems?
Design systems provide a single source of components, patterns, and styles and unify disjointed experiences so that they are visually cohesive and appear to be part of the same ecosystem. As an added bonus, any major visual rebrands or redesigns can be managed at scale through the design system.
What is a design system in UI?
A design system is a collection of reusable UI components. In it, you can define UI elements such as buttons as well as text elements and other elements that you're sure will be reused throughout the design file. This makes the design workflow very easy.
