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:

那副将大喜，这样的重任交到自己手上，相对来说并不危险，只要完成的好还是大功一件,何乐而不为呢？苏角吩咐过后，便离开城头前往城内各处巡视，他是番邑主将，城内的情况必须要有个了解，同时出来也是为了稳定民心。
人们可以从最远30公里的距离看到它们：就像一座咕哝、冒泡的火山，准备喷发，一朵发光的云从地球升起。这就是人们在日出时体验维多利亚瀑布的方式。当地人称之为：“雷声烟”。尤其是在旱季，一场不寻常的迁徙开始了：大象家族从 100 公里外的万基国家公园来到这里。然后发生了一个奇妙而非常罕见的奇观：他们游过赞比西河，就好像他们是一串巨大的珍珠。
