Now that a strong state machine has been written, the logic of this state machine is simple and meticulous. It seems that this code is designed impeccably and this program has no bugs. In fact, this kind of code has been written countless times. For example, to switch the class of a button alternately, like this example, a variable state is often used to record the current state of the button first, and when an event occurs, the next behavior is determined according to this state.

Swift is good at irony. He sympathized with the Irish people's struggle for national independence and wrote a large number of political papers criticizing the British colonial policy, of which "a moderate proposal" is the most famous. This article is perhaps the most tearful satire in the history of English literature. In the tone of a national adviser, the author suggested that the British authorities should eat the babies that the Irish people cannot support, and calculated an economic account for the government, showing that this can save a lot of expenses. He also introduced how to cook babies, how to taste delicious and how to be more nutritious, which broke people's hearts. The author would like to take this opportunity to point out that the British colonial policy is simply eating the meat of the Irish people. This can also be regarded as early black humor.
