Visitor mode is to encapsulate some operations applied to a certain data structure. Once these operations need to be modified, the data structure that accepts this operation can be saved unchanged. Visitor mode is suitable for systems with relatively stable data structures. It reduces the coupling degree between data structures and operations acting on data structures, making the set of operations relatively free to change. The specific structure diagram is as follows:

"WannaCry" and the attack on Wanwei Company both rely on cyber weapons stolen and released by shadow brokers, who effectively use these weapons against the government that develops weapons. WannaCry took advantage of the Windows operating system vulnerability "Eternal Blue" to launch an attack. It used unpatched Microsoft servers to spread malicious software (North Korea used it to spread blackmail software to 200,000 servers worldwide within 24 hours). The attack on Wanwei also used the "Eternal Blue" virus, but at the same time it also used another weapon called "DoublePulsar", which can penetrate the system without undermining the system's security measures. These weapons are designed to carry out silent destruction. They spread rapidly and uncontrollably, and anti-virus software all over the world cannot find them.

From the above command class code, we can see that any operation has an execute method to perform the operation. The above code uses traditional object-oriented programming to implement the command mode. The procedural request call of the command mode is encapsulated in the execute method of the command object. Have we found the above writing code a little cumbersome? We can do this using the callback functions in javascript, In object-oriented, The receiver of the command mode is saved as an attribute of the command object, and the command execution operation is agreed to call the command.execute method. However, if we use the callback function, then the receiver is closed in the environment where the callback function is generated, and the execution operation will be simpler. Only the callback function can be executed. Let's look at the following code:
