Reactronic Front for Web - Transactionally Reactive Frontend Development Framework for Web

Reactronic Front for Web is a JavaScript library that provides
transactionally reactive
facilities for building Web applications.

Transactional reactivity means that state changes are being made in an
isolated data snapshot and then, once atomically applied, are
consistently propagated to corresponding visual components for
(re)rendering. All that is done in automatic, seamless, and fine-grained
way, because reactronic takes full care of tracking dependencies
between visual components (observers) and state objects (observables).
