The policy mode is the packaging of the algorithm, which separates the responsibility of using the algorithm from the algorithm itself and delegates it to different objects. Policy patterns usually wrap a series of algorithms into a series of policy classes. To encapsulate the policy pattern in one sentence is to "encapsulate each algorithm into a different policy class so that they can be interchanged". The following is the structure diagram of the policy mode:
Since it is called, as the name implies, the front section is separated like toes. Of course, this is not just for the sake of good looks. There are other functions and ideas. We will talk about them later.

We are not in a hurry to write the code, We can look at a column first. For example, there are many front-end recruitment information in QQ Group recently. I have also received many phone calls from companies or headhunters asking me if I need to find a job. Of course, I don't plan to find a job now, because I have more spare time to deal with my own affairs, so I also think it is quite good ~ Let's look at the interview process in recruitment first. Interview process for many large companies, such as BAT, the interview process is actually very similar. Therefore, we can summarize the interview process as follows:
一波爆笑声刚止，另一波随起。
无畏而顽皮，她凭本能行事;既是复仇的天使，又是搅屎的人;非常善解人意，直言不讳到无礼的程度。还带着一种非常无礼的幽默感。除了她丈夫几年前去世的事实，很少有人知道她为什么离开原力，这让这个女人成为了一个谜。和Alexa无法抗拒一个谜，所以当前同事和长期的朋友侦探探长基兰赫西请她“咨询”他的棘手的案件，她似乎不情愿。但事实上，她无法抗拒。加入Alexa来解决无法解决的是泡沫，讽刺，雄心勃勃和脚踏的麦迪逊。麦迪逊是一个真正的外向者，她是一名警察的数据分析师，她随时待命，做她最擅长的事情。

又是一轮手油间的拼杀。
For example, I now need to create a div element on the page. Then we definitely need a function to create the div, Now all I need is this function, which is only responsible for creating div elements. It doesn't want to take care of the rest, That is, to realize the principle of single responsibility, Just like Kissy on Taobao, At the beginning, they defined Kissy to do only one thing and did it well. The specific instantiation class in the monomer mode was handled by the agent function. The advantage of doing so was that the specific business logic was separated. The agent only cared about the business logic of the agent. Here, the function of the agent was to instantiate the object and instantiate it only once. Create div code just create div, the others don't care; The following code:
Apple is divided into two recovery modes, one is called DFU mode and the other is recovery mode.
Thus, the consumption of one event in the event sequence will affect the distribution of subsequent events.
One problem with the factory method pattern is that the creation of the class depends on the factory class, that is to say, if you want to expand the program, you must modify the factory class, which violates the closure principle. Therefore, from the design point of view, there are certain problems, how to solve them? We use the abstract factory mode to create multiple factory classes, so that once new functions need to be added, we can directly add new factory classes without modifying the previous code. Because the abstract factory is not very easy to understand, let's look at the diagram first, and then it is easier to understand with the code.
