Plight Of The Butterfly: Object.observe()

on YouTube ↗35m

" summary

Claims that Object.observe delivers change records for raw JS objects and arrays, profiled against V8 and tested in Chrome Canary. Demos actually built: template binding with Polymer, array.observe splices, synthetic change records for accessor/computed properties, a persistence layer that writes to disk (IndexedDB/localStorage), a constraint circle that recomputes radius/area, custom change types with a Notifier API, and a web-audio+canvas live demo — all showing immediate, aggregated notifications rather than blind dirty checking.
