老话说：人来到这世上，分三种人：一种人是来知恩报恩。另一种人是逃债躲债。For example, if we want to implement a JS function, Such as form validation, Then if we don't use the policy pattern in javascript described in the previous chapter to solve the form validation encapsulation code, It is a temporary form validation function written by itself. Certainly without any encapsulation, Then at this time, we will pop up a prompt to the user for whether the two values are equal. If there is a form verification on another page, their judgment method and business logic are basically the same, but the comparison parameters are different. Should we consider writing a form verification code again? So now we can consider using the template method pattern to solve this problem. Common methods are extracted, and different methods are implemented by specific subclasses. This design code also has the advantages of stronger scalability and better code ~)ps：ps：感谢书友【sadamu】两次1888的打赏，感谢诸位的月票支持，谢谢大家。A brief introduction is as follows:2.
