Using destructuring techniques

Destructuring can be used in defn and let. This technique provides flexible ways to extract values for bodies of functions or let expressions. Though destructuring looks a bit unusual for beginners of Clojure and programmers of other languages, it is effective for extracting desired values from the structural data of arguments and binding values.

Getting ready

This recipe uses the math.numeric-tower and core.match functions, so change the :dependency in the project.clj file as follows and restart the REPL, and be ready:

 :dependencies 
  [[org.clojure/clojure "1.8.0"] 
   [org.clojure/math.numeric-tower "0.0.4"] 
   [org.clojure/core.match "0.3.0-alpha4"] 
   ]
