;; Logging is a bit of a lost art. I see people use it the same way they use
;; println debugging, putting in lots of (log/debug "HERE") kind of stuff, and
;; then removing it afterwards.
;;
;; But with a good logging library these logging statements can continue to
;; provide value, even if (especially if) most of the time you turn them off.
;; For this you need to make good use of log levels like
;; error/warn/info/debug/trace. What follows is an illustrated example of how I
;; tend to use them.

為什麼要用 Clojure 語言來開發軟體？

在 Clojure 社群的一個說法：「同樣的工程師使用 Java 來開發軟體、使用 Nodejs 來開發軟體、使用 Clojure 來開發同樣軟體所花費的時間，大約是：5:3:1。」

Part 1: Basic

lesson 1: syntax

0. truth, math, string
1. Intros to list, vector, map, set
2. conj: conj list ,conj vector ,conj map ,conj set
