Clients can use this interpreter to interpret sentences in this language. The interpreter pattern will describe how to interpret these statements using pattern design after having a simple grammar. The language mentioned in the interpreter mode refers to any combination that any interpreter object can interpret. In the interpreter mode, a hierarchical structure of command classes representing grammar needs to be defined, that is, a series of combination rules. Each command object has an interpretation method, which represents the interpretation of the command object. Any permutation and combination of objects in the hierarchy of command objects is a language.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 ~ ~
