Web Components are highlighted as an ideal solution for building Design Systems due to their compatibility with all modern browsers and devices, ease of customization, and potential to drive developer adoption. By utilizing standardized APIs, Web Components provide a single source of truth that works across various platforms, from mobile apps to desktop applications. They offer flexibility in styling and customization, making them adaptable to any brand's design standards. Additionally, they are framework-agnostic, allowing development teams to choose their preferred tools without dependency concerns. The availability of existing Web Component libraries, such as Ionic, facilitates the creation of a Design System without starting from scratch, offering a practical approach for businesses to achieve a consistent and scalable user experience.
