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 ~

In fact, we also need to pay attention to one thing, Because when a packet passes through a chain, All the rules of the current chain are matched, However, there must always be an order when matching. We should match one by one, and we said that rules of the same functional type will gather in a "table". Then, which rules in the "table" will be executed at the front of the "chain"? At this time, there needs to be a priority problem. We also take prerouting "chain" as an illustration.
