These are awesome. They cover all the basics a person might need to know in a new language and they're not one's basic "find out if a number's prime" ones that I'm used. Though I couldn't agree with the author's comment in the intro that program 0 should be "Hello, World!". Just for the sake of going through the motions of actually coding a thing (app or otherwise) in the new language.
