 The function accepts data to be serialized as a first parameter and serialization rules as the second parameter.

 > ℹ️ There is a special value called `SkipSerialization`. It is a unique token that is intended to be used when serialisation traverse does not meet any condition in your serialisation rules and you just need to skip the process for particular case. It has to be this token and not `null` or `undefined` since these two can also have impact on desired data after the serialization.
