Not exactly Functional Reactive Programming, FRB (Bindings) are actually a form of Self Adjusting Computation, but similar in spirit to what you see here, and what you see in Angular. You don’t need #get() and #set(), but it’s implemented using ES5 property descriptors and propagates synchronously. Also, unlike dependent properties like Ember, the dependencies do not have to be repeated—they are inferred from the expression language. https://github.com/montagejs/frb https://github.com/montagejs/frb
