Function: useDependencyValue()
function useDependencyValue<T>(depValue$, defaultValue?): T | undefinedunwrap 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.
