(defn branch
  "A recursive branching tree structure with half-cylinder flowers."
  [level]
  (if (= 0 level)
    [(length 1.5) cylinder]
    [(angle (fn [_] (m/random 3 5))) ry-
     (length (fn [t] (* (m/random 0.75 1.5) (or (:last-length t) 1.5))))
     (map (fn [[a b]] (concat (take 8 (cycle [a b])) (branch (dec level))))     
          [[ry line] [ry- line] [rx line] [rx- line]])]))

Integralist

• defprotocol: defines an interface
• deftype: create a bare-bones object which implements a protocol
• defrecord: creates an immutable persistent map which implements a protocol

Typically you'll use defrecord (or even a basic map);
unless you need some specific Java inter-op,
where by you'll want to use deftype instead.

Note: defprotocol allows you to add new abstractions in a clean way Rather than (like OOP) having polymorphism on the class itself,

React (Virtual) DOM Terminology

In React's terminology, there are five core types that are important to distinguish:

• ReactElement / ReactElement Factory
• ReactNode
• ReactComponent / ReactComponent Class

Clojure Destructuring Tutorial and Cheat Sheet

(Related blog post)

Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.

New React Element Factories and JSX

In React 0.12, we're making a core change to how React.createClass(...) and JSX works.

If you're using JSX in the typical way for all (and only) React components, then this transition will be seamless. Otherwise there are some minor breaking changes described below.
