Standardizing Signals in TC39
summary
TC39 proposes standardizing the core data structures and algorithms for Signals and demonstrates a polyfill that wraps Angular signals, a signal utils library on npm with Stage 3 decorators and reactive proxies, and concrete integrations in lit and Ember. It explains the practical fixes: pull‑based lazy evaluation, topological dependency sorting to avoid the Glitch problem, and detection of cycles. Work is ongoing with public chat rooms, biweekly meetings, and an experimental testbed for cross‑framework reuse.
