Why does anything called &quot;impatient&quot; start with anything else but direct code examples? (Cf. <a href="http:&#x2F;&#x2F;blog.echen.me&#x2F;2012&#x2F;01&#x2F;17&#x2F;quick-introduction-to-ggplot2&#x2F;" rel="nofollow">http:&#x2F;&#x2F;blog.echen.me&#x2F;2012&#x2F;01&#x2F;17&#x2F;quick-introduction-to-ggplot...</a> or <a href="https:&#x2F;&#x2F;www.meteor.com&#x2F;tutorials" rel="nofollow">https:&#x2F;&#x2F;www.meteor.com&#x2F;tutorials</a>)<p>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.
