Why does anything called "impatient" start with anything else but direct code examples? (Cf. http://blog.echen.me/2012/01/17/quick-introduction-to-ggplot2/ http://blog.echen.me/2012/01/17/quick-introduction-to-ggplot... or https://www.meteor.com/tutorials https://www.meteor.com/tutorials) I am impatient and I prefer starting form direct minimalistic code samples (rather than, say, variable types). When I child starts learning LEGO blocks, its rarely from the abstract rules - but from minimalistic example. And I have a strong feeling that the current educational approach mistakes a reference for an introduction.
