Javascript neither supports abstract classes nor has the concept of interfaces. Therefore, be very careful when using the state mode. If you forget to implement the buttonWasPressed method for a state subclass when writing a state subclass, an exception will be thrown when the state switches. Because Context always delegates requests to the buttonWasPressed method of the state object. Therefore, let the abstract method of the abstract parent class throw an exception directly, which will be found at least during the program run.
