Conversations with a six-year-old on functional programming (2018)

4 hours ago

The author explains the concept of functions to his six-year-old son using the analogy of a machine with inputs and outputs.
They create a game called the 'function machine game' where one person thinks of a function and the other guesses it by testing inputs and outputs.
The game becomes popular, with the son also creating his own functions, and the author reflects on the educational value and similarities to other logic games like Zendo.
