With all this crazy attention we've been giving to juxt, it seems wise to learn about the other Clojure functions too! This page is intended to be a convenient springboard for a colossal interactive documentation station that will be put together over time. Since it's running self-hosted Clojurescript, we'll be following this cheat sheet with examples from our good friend ClojureDocs. The killer is that it is interactive. My hope is that it will serve as an extremely handy place where we can find what we need and immediately try stuff out, and when we see it actually evaluate, paste it into our programs! Or at least, if nothing else, I might learn a couple things while doing this...

Basics

Define

(def my-val 5)

my-val

(defn foo [a b c]
	    (* a b c))
	    
(foo 1 2 3)

(ns test)

(defn- foo []
         "World!")
         
(defn bar []
       (str "Hello " (foo)))
       
(foo)

(bar)

(ns playground)

(test/bar)

(test/foo)

(This will not work because foo is private)

(let [a 1 b 2] 
         (+ a b))

(letfn [(twice [x]
           (* x 2))
        (six-times [y]
           (* (twice y) 3))]
  (println "Twice 15 =" (twice 15))
  (println "Six times 15 =" (six-times 15)))

(declare undefined-func)

(defn foo []
         (undefined-func))

That takes care of the Define section. In the next post we'll continue with Branch.
