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:

When "cracking" the sand pile paradox, we often have to set a fixed boundary. If we say "10,000 grains of sand are a pile of sand", then less than 10,000 grains of sand cannot be called a pile of sand. Then it is somewhat unreasonable to distinguish 9999 grains of sand from 10001 grains of sand. This has to set a variable boundary, but what is this boundary? We don't know now. Then the value of "10,000 grains of sand are a pile of sand" originally set as knowledge will be reduced.
