A Deep Dive into Fine-Grained Reactivity and the future of Signals
summary
Shows a working vanilla TypeScript implementation of signals: writes createSignal that returns read/set, builds computed and effect with automatic dependency tracking and cleanup, and demos a counter plus first/last name example where updating either value reruns only dependent effects. Claims this model removes manual dependency lists, outlines Angular and other frameworks adopting signals, and notes a TC39 proposal pushing signals toward standardization.
