Function: useDependencyValue()

function useDependencyValue<T>(depValue$, defaultValue?): T | undefined

unwrap an observable value, return it to the component for rendering, and trigger re-render when value changes

IMPORTANT. Parent and child components better not subscribe to the same observable, otherwise unnecessary re-render would be triggered. Instead, the top-most component should subscribe and pass value of the observable to its offspring, by props or context. Please consider using useDependencyContext and useDependencyContextValue in this case.
