Based on the definition of JavaScript Language specification,Expression a=bThe execution steps, simply put, are:1. The expression A on the left of the equals sign is computed, and the final result must be a reference or a variable;2. Calculate the expression B to the right of the equal sign and get the return value;3.

The main difference is that the input chain is only used to enter the package of the local host, and the output is only used to generate the package from the local host. Therefore, each packet passes through only one of the three chains. The previously forwarded packet passes through all three chains. The other major difference is that-I
