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.

A few days before the fall of Nanjing, the Japanese naval aviation sank the US warship Panai in the Yangtze River. The incident caused quite a stir in the United States and angered the whole country. As the "Panai" was carrying a group of photographers and cameramans, the incident was recorded by video and then produced into a documentary by MGM, which was screened in the United States. In order to prevent the anti-Japanese sentiment in the United States from getting out of control and forcing the U.S. Government to intervene in the war against Japan too early, President Roosevelt ordered the key parts of the film to be cut off so that the fact that the Japanese army deliberately attacked could not be revealed. Even so, the screening of the film has completely reversed the American people's perception of Japan. The public opinion foundation for the United States to support China's resistance to Japan has begun to take shape. The war between Japan and the United States began with Pearl Harbor attack. As for the prelude, many historians believe that when the Panai was sunk, it was already opened. Japan has always insisted on this matter as a mistake. However, Aban entered the curtain and was close to everyone at the top of the Japanese army to expose Japanese lies with first-hand personal experience. The "Panai" incident occurred in the Yangtze River of China and sank a few days before the Nanjing Massacre. It played an important catalytic role in the evolution of the triangular relations between China, Japan and the United States. There are new writings on this matter in the United States at the age of 18. However, the study of Chinese historiography has been completely silent and has remained blank so far. Interestingly, Matsumoto's "Shanghai Times" briefly mentioned the Nanjing Massacre and simply avoided talking about it. Perhaps because the incident involved the darkest scar of the Japanese army, it was really difficult to deal with it properly. Aban's book shows all aspects of the incident to Chinese readers. One is fresh, the other is in-depth and comprehensive, and the reading results are more than general. Of course, about the surging wind and cloud in the United States
