Then in the program it means keeping references to multiple objects, The larger the program, There will be more and more objects, The relationship between them will become more and more complicated. Now if there is an intermediary (if it is our supervisor) to meet the needs of multiple demanders, Then the demander only needs to give all the requirements to our supervisor, who will assign tasks to us according to our workload in turn. In this way, our front-end development does not need to contact with multiple business parties, we only need to contact our supervisor (i.e. Intermediary), which weakens the coupling between objects.
