You still have not understood; Map/Filter/Reduce is a structural pattern. It is based on what one would call "Dataflow Programming" (https://en.wikipedia.org/wiki/Dataflow_programming https://en.wikipedia.org/wiki/Dataflow_programming). A good example is the use of Unix utilities using the pipe operator where any utility in the chain can be of arbitrary complexity.
