Although there are subclasses in java that implement the interfaces of the parent class, But I think javascript can be different from java, It is possible that the parent class in java is an empty class, Subclasses to implement the interface of the parent class, in javascript, I think the common code is completely written in the parent function. If the business logic needs to be changed in the future, or new business logic is added, we can completely use subclasses to rewrite the parent class, so the code has strong scalability and is easier to maintain. Since I am not a professional java, please understand if there is any mistake in describing the knowledge points in java ~ ~

It provides a high-level interface that makes the subsystem easier to use. For example, the customer specialist of Telecom can let the customer specialist complete the services such as charging telephone charges and modifying packages without interacting with various subsystems by himself. The specific class structure diagram is as follows:
