ClojureScript clojure.set？

Question

如何在ClojureScript中使用clojure.set？

我总是得到一个错误.

(def middle-land (set (for [x water-hor
                            y (vec (clojure.set/difference (set (range 0 board-side))
                                                           (set water-ver)))]
                    [x y])))

ReferenceError: clojure is not defined

Answer 1

似乎您需要明确要求命名空间能够使用它:

ClojureScript:cljs.user> (ns core (:require clojure.set))
ClojureScript:core> (clojure.set/difference #{1 2} #{1 4}) ;=> #{2}
