Rethinking UI: Imperative to Declarative
summary
Argues that swapping imperative layouts for Jetpack Compose SwiftUI and React cuts boilerplate and makes state changes deterministic by using unidirectional data flow and a single source of truth. Shows concrete examples: an email list, a lesson card with error/loading/favorited states, and lazy lists that recompose only changed nodes. Claims compiler-level diffing avoids full redraws; Compose is alpha but the examples run conceptually and migrations work best when view models already own UI state.
