External module "hs/prop/index"

prop

• prop<T, K>(hs: HyperScope, hv: HyperValue<T>, propertyName: K): HyperValue<T[K]>

• Allows to make hyper-value from property of another hyper-value (of object-like value). This new property hyper-value will be up-to-date with the actual property and also writes to it when it's changed. It works similar to auto(hs, () => hv.propertyName) but also allows to write to source object. When writing is not needed consider using auto instead of prop
