STATE PATTERN: THE KEY TO SEAMLESS AND PREDICTABLE USER EXPERIENCES

Summary from the TLDR Design newsletter

The State Pattern is a design approach that enables applications to alter their behavior based on internal state changes, ensuring predictable and consistent user experiences through organized state transitions rather than complex conditional logic. By implementing separate state classes that encapsulate specific behaviors and manage transitions between states, such as loading, success, or error, developers create interfaces that respond smoothly and reliably to user actions. When designers and developers collaborate around state awareness, mapping out transitions and behaviors early in development, they build cohesive digital products that feel intuitive and trustworthy to users.
