Make it Classy (2)

In the last exercise, you overrode the class of an object representing a chess game.

To test your understanding, see if you can tell how this affects the four functions for interrogating variable type: class(), typeof(), mode(), and storage.mode().

The chess variable with class "chess_game" is still defined in your workspace. Which of the following statements is true?

You can explore the truth of the statements in the console.

typeof() is a fundamental property that is overridden to match the class() of chess.

mode() is the S-language equivalent of class(), and is overridden to match the class() of chess.

storage.mode() is the S-language equivalent of class(), and is overridden to match the class() of chess.

The typeof(), mode(), and storage.mode() of chess are all still "list".
