Do you put optional parameters at the end?

<introEmbed body={<> Optional parameters should be placed at the end of the method signature as optional ones tend to be less important. You should put the important parameters first. </>} />

public void SaveUserProfile(
  [Optional] string username,
  [Optional] string password,
  string firstName,
  string lastName,
  [Optional] DateTime? birthDate
) {}

❌ Figure: Figure: Bad example - Username and Password are optional and first - they are less important than firstName and lastName and should be put at the end

public void SaveUserProfile(
  string firstName,
  string lastName,
  [Optional] string username,
  [Optional] string password,
  [Optional] DateTime? birthDate
) {}

✅ Figure: Figure: Good example - All the optional parameters are the end

Note: When using optional parameters, please be sure to use named para meters
