I have some confusion about how the function `comp` works, especially as
compared to the threading macro `->>`.
>From the book *Clojure Programming* (pages 70-71 of Chapter 2: Functional
Programming), the following two functions are described as functionally
equivalent:
(def camel->keyword
(comp keyword
str/join
(partial interpose \-)
(partial map str/lower-case)
#(str/split % #"(?<=[a-z])(?=[A-Z])")))
(defn camel->keyword*
[s]
(->> (str/split s #"(?<=[a-z])(?=[A-Z])")
(map str/lower-case)
(interpose \-)
str/join
keyword))
Why does the first function, `camel->keyword`, need to use `partial` with
the
`map` and `interpose` functions? The second function, `camel->keyword*`,
does
not need to use `partial`.
