Do you know why building in Figma is no longer such a tedious process? Because with variables, modes, and expressions, designers can finally create dynamic, interactive prototypes without duplicating endless frames or relying on developers. You can update prices in real-time, show or hide content based on user actions, and simulate complete user flows - all within the design itself. This brings prototyping much closer to how the final product actually behaves. We used this approach to build smarter, more testable flows - and this guide helped a lot - Interactive prototypes
