Module "dispatch"

map

• map<ChildAction, ParentAction>(actionMapper: (childAction: ChildAction) => ParentAction, dispatch: Dispatch<ParentAction>): Dispatch<ChildAction>

• Maps a parent dispatch function to child dispatch function. The resulting function is memoized so it will be consistent for future calls. This makes it possible to avoid re-render in e.g. react becuase the dispach prop will not change like it would if a lambda like (a) => dispatch(mapper(a)) was used.
