3. Some classes, such as the core trading engine of the exchange, control the trading process. If multiple classes can be created, the system will be completely messed up. (For example, if there are multiple commanders in an army who command at the same time, there will definitely be a mess), so only by using the singleton mode can the core transaction server independently control the whole process.
In the above code, we use three functions, order500, order200, orderNormal to handle its own business logic, If the current own function cannot handle things, We pass it to the following function to handle it. By analogy, Until there is a function that can handle him, Otherwise, the responsibility chain mode will leave the chain directly, telling that it cannot be processed and throwing an error prompt. Although the above code can be used as the responsibility chain mode, we can see from the above code that the Order500 function depends on functions such as Order200, so there must be this function, which also violates the open-closed principle in object-oriented. Let's continue to understand writing flexible and detachable responsibility chain nodes.

Let's understand such a problem first, If our front-end development needs are the needs given to us by the demand side, It is possible that a front-end developer will deal with multiple demanders, Therefore, it will keep in touch with multiple demand parties. 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.
