" summary

Argues that declarative code is code where each thing is declared and controlled in one place, which cuts bugs and simplifies debugging; shows that React useState + event handlers produce MVC-style external control that caused Facebook’s infamous unseen-message bug and that collocating control fixes it. Demonstrates tools and tradeoffs: TanStack Query replaces verbose useEffect fetching, RxJS enables fully declarative async flows, and modern signals (Angular) converge primitives; presents a small library (State Adapt) and refactors that reduce lines and complexity.
