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.

This time we went to Wangwan Village, Xichuan Town, Qin'an County, where we started my social practice this holiday. Practice, on the one hand, is to apply the theoretical knowledge we have learned in school to objective reality, so that the theoretical knowledge we have learned can be used. If we only learn but not practice, then what we have learned is equal to zero. On the other hand, practice can lay the foundation for finding a job in the future. Through this period of internship, I learned something that I could not learn in school. Because the environment is different, the people and things contacted are different, and the things learned from them are naturally different. We should learn to learn from practice and practice from study.
