Declarative by default
summary
Argues that making projects declarative by default reduces cognitive load and makes large React apps more maintainable and easier to evolve, citing concrete patterns: functions-as-components, pure functions, immutability, and the functional core, imperative shell separation. Shows a real useLazyImage hook that wraps an IntersectionObserver-based imperative implementation into a declarative component, and points to practical tools like React Router, React Query, Zod and Framer Motion as examples of declarative APIs that help teams stay in the “pit of success.”
