如何在ClojureScript中使用命名参数？

Question

在clojure中，我可以使用defnk来获取命名参数。我如何在ClojureScript中实现同样的功能？

Answer 1

在ClojureScript命名ARGS功能是相同的Clojure：

(defn f [x & {:keys [a b]}] 
    (println (str "a is " a " and b is " b))) 

(f 1) 
; a is and b is 

(f 1 :a 42) 
; a is 42 and b is 

(f 1 :a 42 :b 108) 
; a is 42 and b is 108 

如果你想默认值，然后改变原来到：

(defn f [x & {:keys [a b] :or {a 999 b 9}}] 
    (println (str "a is " a " and b is " b))) 

(f 1) 
; a is 999 and b is 9 

这与漂亮的答案对于Clojure - named arguments
